Title

i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request

Summary

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when the ring is being stopped. Depending on timing between ring stop request completion, interrupt handler removal and code execution this may lead to a NULL pointer dereference in hci_dma_irq_handler() if it gets to run after the io_data pointer is set to NULL in hci_dma_cleanup(). Prevent this my masking the ring interrupts before ring stop request.

GHSA-QRF2-8JCF-FV7V

Vulnerability from github – Published: 2025-01-11 15:30 – Updated: 2025-11-03 21:32

Details

In the Linux kernel, the following vulnerability has been resolved:

i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request

Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when the ring is being stopped. Depending on timing between ring stop request completion, interrupt handler removal and code execution this may lead to a NULL pointer dereference in hci_dma_irq_handler() if it gets to run after the io_data pointer is set to NULL in hci_dma_cleanup().

Prevent this my masking the ring interrupts before ring stop request.

Severity

5.5 (Medium)

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

net: wwan: t7xx: Fix FSM command timeout issue

When driver processes the internal state change command, it use an asynchronous thread to process the command operation. If the main thread detects that the task has timed out, the asynchronous thread will panic when executing the completion notification because the main thread completion object has been released.

In the Linux kernel, the following vulnerability has been resolved:

i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request

Prevent this my masking the ring interrupts before ring stop request.(CVE-2024-45828)

In the Linux kernel, the following vulnerability has been resolved:

ethtool: fail closed if we can't get max channel used in indirection tables

Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with active RSS contexts") proves that allowing indirection table to contain channels with out of bounds IDs may lead to crashes. Currently the max channel check in the core gets skipped if driver can't fetch the indirection table or when we can't allocate memory.

Both of those conditions should be extremely rare but if they do happen we should try to be safe and fail the channel change.(CVE-2024-46834)

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7921: fix NULL pointer access in mt7921_ipv6_addr_change

When disabling wifi mt7921_ipv6_addr_change() is called as a notifier. At this point mvif->phy is already NULL so we cannot use it here.(CVE-2024-46860)

In the Linux kernel, the following vulnerability has been resolved:

usbnet: ipheth: do not stop RX on failing RX callback

RX callbacks can fail for multiple reasons:

Payload too short
Payload formatted incorrecly (e.g. bad NCM framing)
Lack of memory

None of these should cause the driver to seize up.

Make such failures non-critical and continue processing further incoming URBs.(CVE-2024-46861)

In the Linux kernel, the following vulnerability has been resolved:

nvme-rdma: unquiesce admin_q before destroy it

This due to we have quiesced admi_q before cancel requests, but forgot to unquiesce before destroy it, as a result we fail to drain the pending requests, and hang on blk_mq_freeze_queue_wait() forever. Here try to reuse nvme_rdma_teardown_admin_queue() to fix this issue and simplify the code.(CVE-2024-49569)

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Don't call cleanup on profile rollback failure

When profile rollback fails in mlx5e_netdev_change_profile, the netdev profile var is left set to NULL. Avoid a crash when unloading the driver by not calling profile->cleanup in such a case.

This was encountered while testing, with the original trigger that the wq rescuer thread creation got interrupted (presumably due to Ctrl+C-ing modprobe), which gets converted to ENOMEM (-12) by mlx5e_priv_init, the profile rollback also fails for the same reason (signal still active) so the profile is left as NULL, leading to a crash later in _mlx5e_remove.

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: Get rid of userspace_irqchip_in_use

Improper use of userspace_irqchip_in_use led to syzbot hitting the following WARN_ON() in kvm_timer_update_irq():

WARNING: CPU: 0 PID: 3281 at arch/arm64/kvm/arch_timer.c:459 kvm_timer_update_irq+0x21c/0x394 Call trace: kvm_timer_update_irq+0x21c/0x394 arch/arm64/kvm/arch_timer.c:459 kvm_timer_vcpu_reset+0x158/0x684 arch/arm64/kvm/arch_timer.c:968 kvm_reset_vcpu+0x3b4/0x560 arch/arm64/kvm/reset.c:264 kvm_vcpu_set_target arch/arm64/kvm/arm.c:1553 [inline] kvm_arch_vcpu_ioctl_vcpu_init arch/arm64/kvm/arm.c:1573 [inline] kvm_arch_vcpu_ioctl+0x112c/0x1b3c arch/arm64/kvm/arm.c:1695 kvm_vcpu_ioctl+0x4ec/0xf74 virt/kvm/kvm_main.c:4658 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:907 [inline] __se_sys_ioctl fs/ioctl.c:893 [inline] __arm64_sys_ioctl+0x108/0x184 fs/ioctl.c:893 __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline] invoke_syscall+0x78/0x1b8 arch/arm64/kernel/syscall.c:49 el0_svc_common+0xe8/0x1b0 arch/arm64/kernel/syscall.c:132 do_el0_svc+0x40/0x50 arch/arm64/kernel/syscall.c:151 el0_svc+0x54/0x14c arch/arm64/kernel/entry-common.c:712 el0t_64_sync_handler+0x84/0xfc arch/arm64/kernel/entry-common.c:730 el0t_64_sync+0x190/0x194 arch/arm64/kernel/entry.S:598

The following sequence led to the scenario: - Userspace creates a VM and a vCPU. - The vCPU is initialized with KVM_ARM_VCPU_PMU_V3 during KVM_ARM_VCPU_INIT. - Without any other setup, such as vGIC or vPMU, userspace issues KVM_RUN on the vCPU. Since the vPMU is requested, but not setup, kvm_arm_pmu_v3_enable() fails in kvm_arch_vcpu_run_pid_change(). As a result, KVM_RUN returns after enabling the timer, but before incrementing 'userspace_irqchip_in_use': kvm_arch_vcpu_run_pid_change() ret = kvm_arm_pmu_v3_enable() if (!vcpu->arch.pmu.created) return -EINVAL; if (ret) return ret; [...] if (!irqchip_in_kernel(kvm)) static_branch_inc(&userspace_irqchip_in_use); - Userspace ignores the error and issues KVM_ARM_VCPU_INIT again. Since the timer is already enabled, control moves through the following flow, ultimately hitting the WARN_ON(): kvm_timer_vcpu_reset() if (timer->enabled) kvm_timer_update_irq() if (!userspace_irqchip()) ret = kvm_vgic_inject_irq() ret = vgic_lazy_init() if (unlikely(!vgic_initialized(kvm))) if (kvm->arch.vgic.vgic_model != KVM_DEV_TYPE_ARM_VGIC_V2) return -EBUSY; WARN_ON(ret);

Theoretically, since userspace_irqchip_in_use's functionality can be simply replaced by '!irqchip_in_kernel()', get rid of the static key to avoid the mismanagement, which also helps with the syzbot issue.(CVE-2024-53195)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: IDLETIMER: Fix for possible ABBA deadlock

Deletion of the last rule referencing a given idletimer may happen at the same time as a read of its file in sysfs:

| ====================================================== | WARNING: possible circular locking dependency detected | 6.12.0-rc7-01692-g5e9a28f41134-dirty #594 Not tainted | ------------------------------------------------------ | iptables/3303 is trying to acquire lock: | ffff8881057e04b8 (kn->active#48){++++}-{0:0}, at: __kernfs_remove+0x20 | | but task is already holding lock: | ffffffffa0249068 (list_mutex){+.+.}-{3:3}, at: idletimer_tg_destroy_v] | | which lock already depends on the new lock.

A simple reproducer is:

#!/bin/bash

iptables -D INPUT -i foo -j IDLETIMER --timeout 10 --label "testme"
done &

done

Avoid this by freeing list_mutex right after deleting the element from the list, then continuing with the teardown.(CVE-2024-54683)

Debugging Analysis:

The following ftrace log shows that the lockup CPU spends too much time iterating vmap_nodes and flushing TLB when purging vm_area structures. (Some info is trimmed).

kworker: funcgraph_entry: | drain_vmap_area_work() { kworker: funcgraph_entry: | mutex_lock() { kworker: funcgraph_entry: 1.092 us | __cond_resched(); kworker: funcgraph_exit: 3.306 us | } ... ... kworker: funcgraph_entry: | flush_tlb_kernel_range() { ... ... kworker: funcgraph_exit: # 7533.649 us | } ... ... kworker: funcgraph_entry: 2.344 us | mutex_unlock(); kworker: funcgraph_exit: $ 23871554 us | }

The drain_vmap_area_work() spends over 23 seconds.

There are 2805 flush_tlb_kernel_range() calls in the ftrace log. * One is called in __purge_vmap_area_lazy(). * Others are called by purge_vmap_node->kasan_release_vmalloc. purge_vmap_node() iteratively releases kasan vmalloc allocations and flushes TLB for each vmap_area. - [Rough calculation] Each flush_tlb_kernel_range() runs about 7.5ms. -- 2804 * 7.5ms = 21.03 seconds. -- That's why a soft lock is triggered.
Extending the soft lockup time can work around the issue (For example, # echo ---truncated---(CVE-2024-56559)

icmp_route_lookup() create input routes for locally generated packets while xfrm relookup ICMP traffic.Then it will set input route (dst->out = ip_rt_bug) to skb for DESTUNREACH.

For ICMP err triggered by locally generated packets, dst->dev of output route is loopback. Generally, xfrm relookup verification is not required on loopback interfaces (net.ipv4.conf.lo.disable_xfrm = 1).

Skip icmp relookup for locally generated packets to fix it.(CVE-2024-56647)

ipv6: Fix soft lockups in fib6_select_path under high next hop churn

Soft lockups have been observed on a cluster of Linux-based edge routers located in a highly dynamic environment. Using the bird service, these routers continuously update BGP-advertised routes due to frequently changing nexthop destinations, while also managing significant IPv6 traffic. The lockups occur during the traversal of the multipath circular linked-list in the fib6_select_path function, particularly while iterating through the siblings in the list. The issue typically arises when the nodes of the linked list are unexpectedly deleted concurrently on a different core—indicated by their 'next' and 'previous' elements pointing back to the node itself and their reference count dropping to zero. This results in an infinite loop, leading to a soft lockup that triggers a system panic via the watchdog timer.

Apply RCU primitives in the problematic code sections to resolve the issue. Where necessary, update the references to fib6_siblings to annotate or use the RCU APIs.

Include a test script that reproduces the issue. The script periodically updates the routing table while generating a heavy load of outgoing IPv6 traffic through multiple iperf3 clients. It consistently induces infinite soft lockups within a couple of minutes.

In the Linux kernel, the following vulnerability has been resolved:

soc: imx8m: Probe the SoC driver as platform driver

With driver_async_probe=* on kernel command line, the following trace is produced because on i.MX8M Plus hardware because the soc-imx8m.c driver calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock driver is not yet probed. This was not detected during regular testing without driver_async_probe.

Convert the SoC code to platform driver and instantiate a platform device in its current device_initcall() to probe the platform driver. Rework .soc_revision callback to always return valid error code and return SoC revision via parameter. This way, if anything in the .soc_revision callback return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get retried later.

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Skip restore TC rules for vport rep without loaded flag

During driver unload, unregister_netdev is called after unloading vport rep. So, the mlx5e_rep_priv is already freed while trying to get rpriv->netdev, or walk rpriv->tc_ht, which results in use-after-free. So add the checking to make sure access the data of vport rep which is still loaded.(CVE-2024-57801)

In the Linux kernel, the following vulnerability has been resolved:

s390/cpum_sf: Handle CPU hotplug remove during sampling

CPU hotplug remove handling triggers the following function call sequence:

CPUHP_AP_PERF_S390_SF_ONLINE --> s390_pmu_sf_offline_cpu() ... CPUHP_AP_PERF_ONLINE --> perf_event_exit_cpu()

The s390 CPUMF sampling CPU hotplug handler invokes:

s390_pmu_sf_offline_cpu() +--> cpusf_pmu_setup() +--> setup_pmc_cpu() +--> deallocate_buffers()

This function de-allocates all sampling data buffers (SDBs) allocated for that CPU at event initialization. It also clears the PMU_F_RESERVED bit. The CPU is gone and can not be sampled.

With the event still being active on the removed CPU, the CPU event hotplug support in kernel performance subsystem triggers the following function calls on the removed CPU:

perf_event_exit_cpu() +--> perf_event_exit_cpu_context() +--> __perf_event_exit_context() +--> __perf_remove_from_context() +--> event_sched_out() +--> cpumsf_pmu_del() +--> cpumsf_pmu_stop() +--> hw_perf_event_update()

to stop and remove the event. During removal of the event, the sampling device driver tries to read out the remaining samples from the sample data buffers (SDBs). But they have already been freed (and may have been re-assigned). This may lead to a use after free situation in which case the samples are most likely invalid. In the best case the memory has not been reassigned and still contains valid data.

Remedy this situation and check if the CPU is still in reserved state (bit PMU_F_RESERVED set). In this case the SDBs have not been released an contain valid data. This is always the case when the event is removed (and no CPU hotplug off occured). If the PMU_F_RESERVED bit is not set, the SDB buffers are gone.(CVE-2024-57849)

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: pltfrm: Dellocate HBA during ufshcd_pltfrm_remove()

This will ensure that the scsi host is cleaned up properly using scsi_host_dev_release(). Otherwise, it may lead to memory leaks.(CVE-2024-57872)

In the Linux kernel, the following vulnerability has been resolved:

ALSA: seq: oss: Fix races at processing SysEx messages

OSS sequencer handles the SysEx messages split in 6 bytes packets, and ALSA sequencer OSS layer tries to combine those. It stores the data in the internal buffer and this access is racy as of now, which may lead to the out-of-bounds access.

As a temporary band-aid fix, introduce a mutex for serializing the process of the SysEx message packets.(CVE-2024-57893)

In the Linux kernel, the following vulnerability has been resolved:

iio: adc: at91: call input_free_device() on allocated iio_dev

Current implementation of at91_ts_register() calls input_free_deivce() on st->ts_input, however, the err label can be reached before the allocated iio_dev is stored to st->ts_input. Thus call input_free_device() on input instead of st->ts_input.(CVE-2024-57904)

In the Linux kernel, the following vulnerability has been resolved:

selinux: ignore unknown extended permissions

When evaluating extended permissions, ignore unknown permissions instead of calling BUG(). This commit ensures that future permissions can be added without interfering with older kernels.(CVE-2024-57931)

In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic-v3-its: Don't enable interrupts in its_irq_set_vcpu_affinity()

The following call-chain leads to enabling interrupts in a nested interrupt disabled section:

irq_set_vcpu_affinity() irq_get_desc_lock() raw_spin_lock_irqsave() <--- Disable interrupts its_irq_set_vcpu_affinity() guard(raw_spinlock_irq) <--- Enables interrupts when leaving the guard() irq_put_desc_unlock() <--- Warns because interrupts are enabled

This was broken in commit b97e8a2f7130, which replaced the original raw_spin_[un]lock() pair with guard(raw_spinlock_irq).

Fix the issue by using guard(raw_spinlock).

In the Linux kernel, the following vulnerability has been resolved:

sched: sch_cake: add bounds checks to host bulk flow fairness counts

Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access.

To avoid any such logic errors causing out of bounds memory accesses, this commit factors out all accesses to the per-host bulk flow counters to a series of helpers that perform bounds-checking before any increments and decrements. This also has the benefit of improving readability by moving the conditional checks for the flow mode into these helpers, instead of having them spread out throughout the code (which was the cause of the original logic error).

As part of this change, the flow quantum calculation is consolidated into a helper function, which means that the dithering applied to the ost load scaling is now applied both in the DRR rotation and when a sparse flow's quantum is first initiated. The only user-visible effect of this is that the maximum packet size that can be sent while a flow stays sparse will now vary with +/- one byte in some cases. This should not make a noticeable difference in practice, and thus it's not worth complicating the code to preserve the old behaviour.(CVE-2025-21647)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: conntrack: clamp maximum hashtable size to INT_MAX

Use INT_MAX as maximum size for the conntrack hashtable. Otherwise, it is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when resizing hashtable because __GFP_NOWARN is unset. See:

0708a0afe291 ("mm: Consider __GFP_NOWARN flag for oversized kvmalloc() calls")

Note: hashtable resize is only possible from init_netns.(CVE-2025-21648)

In the Linux kernel, the following vulnerability has been resolved:

In the Linux kernel, the following vulnerability has been resolved: fs/proc: fix softlockup in __read_vmcore (part 2) Since commit 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") the number of softlockups in __read_vmcore at kdump time have gone down, but they still happen sometimes. In a memory constrained environment like the kdump image, a softlockup is not just a harmless message, but it can interfere with things like RCU freeing memory, causing the crashdump to get stuck. The second loop in __read_vmcore has a lot more opportunities for natural sleep points, like scheduling out while waiting for a data write to happen, but apparently that is not always enough. Add a cond_resched() to the second loop in __read_vmcore to (hopefully) get rid of the softlockups.(CVE-2025-21694)

Using the `bird` service, these\nrouters continuously update BGP-advertised routes due to frequently\nchanging nexthop destinations, while also managing significant IPv6\ntraffic. The lockups occur during the traversal of the multipath\ncircular linked-list in the `fib6_select_path` function, particularly\nwhile iterating through the siblings in the list. The issue typically\narises when the nodes of the linked list are unexpectedly deleted\nconcurrently on a different core\u2014indicated by their \u0026apos;next\u0026apos; and\n\u0026apos;previous\u0026apos; elements pointing back to the node itself and their reference\ncount dropping to zero. This results in an infinite loop, leading to a\nsoft lockup that triggers a system panic via the watchdog timer.\n\nApply RCU primitives in the problematic code sections to resolve the\nissue.

So, the mlx5e_rep_priv is already freed while trying to get\nrpriv-\u0026gt;netdev, or walk rpriv-\u0026gt;tc_ht, which results in use-after-free.\nSo add the checking to make sure access the data of vport rep which is\nstill loaded.(CVE-2024-57801)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\ns390/cpum_sf: Handle CPU hotplug remove during sampling\n\nCPU hotplug remove handling triggers the following function\ncall sequence:\n\n   CPUHP_AP_PERF_S390_SF_ONLINE  --\u0026gt; s390_pmu_sf_offline_cpu()\n   ...\n   CPUHP_AP_PERF_ONLINE          --\u0026gt; perf_event_exit_cpu()\n\nThe s390 CPUMF sampling CPU hotplug handler invokes:\n\n s390_pmu_sf_offline_cpu()\n +--\u0026gt;  cpusf_pmu_setup()\n       +--\u0026gt; setup_pmc_cpu()\n            +--\u0026gt; deallocate_buffers()\n\nThis function de-allocates all sampling data buffers (SDBs) allocated\nfor that CPU at event initialization. It also clears the\nPMU_F_RESERVED bit. The CPU is gone and can not be sampled.\n\nWith the event still being active on the removed CPU, the CPU event\nhotplug support in kernel performance subsystem triggers the\nfollowing function calls on the removed CPU:\n\n  perf_event_exit_cpu()\n  +--\u0026gt; perf_event_exit_cpu_context()\n       +--\u0026gt; __perf_event_exit_context()\n\t    +--\u0026gt; __perf_remove_from_context()\n\t         +--\u0026gt; event_sched_out()\n\t              +--\u0026gt; cpumsf_pmu_del()\n\t                   +--\u0026gt; cpumsf_pmu_stop()\n                                +--\u0026gt; hw_perf_event_update()\n\nto stop and remove the event. During removal of the event, the\nsampling device driver tries to read out the remaining samples from\nthe sample data buffers (SDBs). But they have already been freed\n(and may have been re-assigned). This may lead to a use after free\nsituation in which case the samples are most likely invalid. In the\nbest case the memory has not been reassigned and still contains\nvalid data.\n\nRemedy this situation and check if the CPU is still in reserved\nstate (bit PMU_F_RESERVED set). In this case the SDBs have not been\nreleased an contain valid data. This is always the case when\nthe event is removed (and no CPU hotplug off occured).\nIf the PMU_F_RESERVED bit is not set, the SDB buffers are gone.(CVE-2024-57849)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: pltfrm: Dellocate HBA during ufshcd_pltfrm_remove()\n\nThis will ensure that the scsi host is cleaned up properly using\nscsi_host_dev_release(). Otherwise, it may lead to memory leaks.(CVE-2024-57872)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nALSA: seq: oss: Fix races at processing SysEx messages\n\nOSS sequencer handles the SysEx messages split in 6 bytes packets, and\nALSA sequencer OSS layer tries to combine those.

This also has the benefit of improving\nreadability by moving the conditional checks for the flow mode into\nthese helpers, instead of having them spread out throughout the\ncode (which was the cause of the original logic error).\n\nAs part of this change, the flow quantum calculation is consolidated\ninto a helper function, which means that the dithering applied to the\nost load scaling is now applied both in the DRR rotation and when a\nsparse flow\u0026apos;s quantum is first initiated. The only user-visible effect\nof this is that the maximum packet size that can be sent while a flow\nstays sparse will now vary with +/- one byte in some cases. This should\nnot make a noticeable difference in practice, and thus it\u0026apos;s not worth\ncomplicating the code to preserve the old behaviour.(CVE-2025-21647)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: conntrack: clamp maximum hashtable size to INT_MAX\n\nUse INT_MAX as maximum size for the conntrack hashtable.
