Title
PCI: altera: Fix resource leaks on probe failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: altera: Fix resource leaks on probe failure
The chained IRQ handler is set during probe, but is only removed during the
driver remove(). If pci_host_probe() fails, the handler and INTx IRQ
domain remain set even though the devm-managed host bridge storage
containing struct altera_pcie will be released, leaving the handler with
a stale data pointer.
Interrupts are also enabled before pci_host_probe() is called. If probe
fails after that point, the controller interrupt source should be disabled
before the chained handler and INTx domain are removed.
So set the chained handler only after the INTx domain has been created.
Disable controller interrupts during IRQ teardown, and tear the IRQ setup
down if pci_host_probe() fails.

Title
vfio/mlx5: Fix racy bitfields and tighten struct layout
Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/mlx5: Fix racy bitfields and tighten struct layout
Bitfield operations are not atomic, they use a read-modify-write
pattern, therefore we should be careful not to pack bitfields that
can be concurrently updated into the same storage unit.
This split takes a binary approach: flags that are only modified
pre/post open/close remain bitfields, flags modified from user
action, including actions that reach across to another device (ex.
reset) use dedicated storage units.
Note mlx5_vhca_page_tracker.status is relocated to fill the alignment
hole this split exposes.
Bitfield justifications:
migrate_cap: written only in mlx5vf_cmd_set_migratable() at probe
chunk_mode: written only in mlx5vf_cmd_set_migratable() at probe
mig_state_cap: written only in mlx5vf_cmd_set_migratable() at probe
Dedicated storage units:
mdev_detach: written in the VF attach/detach event notifier
mlx5fv_vf_event() at runtime
log_active: written in mlx5vf_start_page_tracker()/
mlx5vf_stop_page_tracker() during runtime dirty tracking
deferred_reset: written in mlx5vf_state_mutex_unlock()/
mlx5vf_pci_aer_reset_done() during runtime reset handling
is_err: set by tracker error handling and dirty-log polling at runtime
object_changed: set by tracker event handling and cleared by dirty-log
polling at runtime
Severity
No CVSS data available.

Title
ALSA: hda/cs35l41: Fix firmware load work teardown
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda/cs35l41: Fix firmware load work teardown
cs35l41_hda creates ALSA controls whose private data points at the
cs35l41_hda object. The firmware load control can also queue
fw_load_work.
Those controls are not removed on component unbind, and device remove
only cancels fw_load_work through cs35l41_remove_dsp(). That helper is
skipped when halo_initialized is false. With firmware_autostart
disabled, a firmware load can be requested before the DSP has been
initialized. If the component or device is removed before the queued
work runs, the worker can run after teardown and dereference driver
state that is no longer valid.
Track the created controls and remove them on unbind so no new control
callback can reach the driver data or queue more work. Then cancel
fw_load_work to drain any request that was already queued. Also cancel
the work unconditionally during device remove before runtime PM teardown.
Severity
7.8 (High)

The ioctl path contains no capability, namespace, or administrative privilege check.\nUI:N - Exploitation requires no victim to open content or perform an interactive action.\nS:U - The vulnerable driver and the affected kernel resources are governed by the same kernel security authority.\nC:H - The heap use-after-free permits attacker-influenced reuse and disclosure of freed kernel object contents, potentially supporting arbitrary kernel memory reads.\nI:H - The freed object embeds mutable workqueue list state and a function pointer that is subsequently invoked, making kernel memory corruption and control-flow hijacking defensible.\nA:H - Stale control accesses or corrupted queued work can cause a kernel oops, panic, or workqueue corruption, resulting in complete system unavailability."

Title
ALSA: aoa: check snd_ctl_new1() return value
Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: aoa: check snd_ctl_new1() return value
snd_ctl_new1() can return NULL when memory allocation fails. In
layout.c, the function does not check the return value before
dereferencing ctl->id.name or passing to aoa_snd_ctl_add(), which can
lead to a NULL pointer dereference.
Add NULL checks after snd_ctl_new1() calls and return early if any
fails.
Severity
No CVSS data available.

Title
iio: pressure: mpl115: fix runtime PM leak on read error
Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: pressure: mpl115: fix runtime PM leak on read error
mpl115_read_raw() takes a runtime PM reference with pm_runtime_get_sync()
before reading the processed pressure or raw temperature, but on the read
error path it returns without calling pm_runtime_put_autosuspend(). Each
failed read therefore leaks a runtime PM reference and prevents the device
from autosuspending.
Drop the reference before checking the return value so both the success
and error paths are balanced.
Severity
No CVSS data available.

Title
x86/bugs: Enable IBPB flush on BPF JIT allocation
Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/bugs: Enable IBPB flush on BPF JIT allocation
Enable hardening against JIT spraying when Spectre-v2 mitigations are in
use. Specifically, issue an IBPB flush on BPF JIT memory reuse. Skip
enabling the IBPB flush if the BPF dispatcher is already using a retpoline
sequence.
This hardening applies only when BPF-JIT is in use. Guard the enabling
under CONFIG_BPF_JIT so that bugs.c still builds with CONFIG_BPF_JIT=n.
Severity
No CVSS data available.

Title
bpf: Support for hardening against JIT spraying
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Support for hardening against JIT spraying
The BPF JIT allocator packs many small programs into larger executable
allocations and reuses space within those allocations as programs are
loaded and freed. When fresh code is written into space that a previous
program occupied, an indirect jump into the new program can reuse a branch
prediction left behind by the old one.
Flush the indirect branch predictors before reusing JIT memory so that
indirect jumps into a newly written program don't reuse predictions from an
old program that occupied the same space.
Introduce bpf_arch_pred_flush_enabled static key and bpf_arch_pred_flush
static call for flushing the branch predictors on JIT memory reuse.
Architectures that need a flush, can update it to a predictor flush
function. By default, its a NOP and does not emit any CALL.
Allocations larger than a pack are not covered by this flush. That is safe
because cBPF programs (the unprivileged attack surface) are bounded well
below a pack size. Issue a warning if this assumption is ever violated
while the flush is active.
Severity
No CVSS data available.

Title
rust: block: fix GenDisk cleanup paths
Summary
In the Linux kernel, the following vulnerability has been resolved:
rust: block: fix GenDisk cleanup paths
GenDiskBuilder::build() still has fallible work after
__blk_mq_alloc_disk(), but its error path only recovers the
foreign queue data. That leaks the temporary gendisk and
request_queue until later teardown. If the caller moved the last
Arc<TagSet<T>> into build(), the leaked queue can retain blk-mq
state after the tag set is dropped.
Fix the pre-registration failure path by dropping the temporary
gendisk reference with put_disk() before recovering queue_data,
so disk_release() can tear down the owned queue.
Also pair GenDisk::drop() with put_disk() after del_gendisk().
Once a Rust GenDisk has been added with device_add_disk(),
del_gendisk() only unregisters it; the final gendisk reference
still has to be dropped to complete the release path.
Severity
No CVSS data available.

Title
ACPI: NFIT: core: Fix acpi_nfit_init() error cleanup
Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: NFIT: core: Fix acpi_nfit_init() error cleanup
If acpi_nfit_init() fails after adding the acpi_desc object to the
acpi_descs list, that object is never removed from that list because
the acpi_nfit_shutdown() devm action is not added for the NFIT device
in that case. Next, the acpi_nfit_init() failure causes
acpi_nfit_probe() to fail, the acpi_desc object is freed, and a
dangling pointer is left behind in the acpi_descs. Any subsequent
ACPI Machine Check Exception will trigger nfit_handle_mce() which
iterates over acpi_descs and so a use-after-free will occur.
Moreover, if acpi_nfit_probe() returns 0 after installing a notify
handler for the NFIT device and without allocating the acpi_desc
object and setting the NFIT device's driver data pointer, the
acpi_desc object will be allocated by acpi_nfit_update_notify()
and acpi_nfit_init() will be called to initialize it. Regardless
of whether or not acpi_nfit_init() fails in that case, the
acpi_nfit_shutdown() devm action is not added for the NFIT device
and acpi_desc is never removed from the acpi_descs list. If the
acpi_desc object is freed subsequently on driver removal, any
subsequent ACPI MCE will lead to a use-after-free like in the
previous case.
To address the first issue mentioned above, make acpi_nfit_probe()
call acpi_nfit_shutdown() directly on acpi_nfit_init() failures and
to address the other one, add a remove callback to the driver and
make it call acpi_nfit_shutdown(). Also, since it is now possible to
pass NULL to acpi_nfit_shutdown() or the acpi_desc object passed to it
may not have been initialized, add checks against NULL for acpi_desc and
its nvdimm_bus field to that function and make acpi_nfit_unregister()
clear the latter after unregistering the NVDIMM bus.

net/sched: cls_api: Handle TC_ACT_CONSUMED in tcf_qevent_handle
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: cls_api: Handle TC_ACT_CONSUMED in tcf_qevent_handle
tcf_classify() can return TC_ACT_CONSUMED while the skb is held by the
defragmentation engine (e.g. act_ct on out-of-order fragments). When
that happens the skb is no longer owned by the caller and must not be
touched again.
tcf_qevent_handle() did not handle TC_ACT_CONSUMED: it fell through the
switch and returned the skb to the caller as if classification had
passed. The only qdisc that wires up qevents today is RED, via three call sites
(qe_mark on RED_PROB_MARK/HARD_MARK, qe_early_drop on congestion_drop)
red_enqueue() was continuing to operate on an skb it no longer owns in this
case -- enqueueing it, dropping it, or updating statistics. Resulting in a UAF.
tc qdisc add dev eth0 root handle 1: red ... qevent early_drop block 10
tc filter add block 10 ... action ct
(with ct defrag enabled and traffic that produces out-of-order
fragments, e.g. a fragmented UDP stream)
Handle TC_ACT_CONSUMED in tcf_qevent_handle() the same way the ingress
and egress fast paths do: treat it as stolen and return NULL without
touching the skb. Unlike the TC_ACT_STOLEN case, the skb must not be
dropped/freed here, as it is no longer owned by us.

When\nthat happens the skb is no longer owned by the caller and must not be\ntouched again.\n\ntcf_qevent_handle() did not handle TC_ACT_CONSUMED: it fell through the\nswitch and returned the skb to the caller as if classification had\npassed. The only qdisc that wires up qevents today is RED, via three call sites\n(qe_mark on RED_PROB_MARK/HARD_MARK, qe_early_drop on congestion_drop)\nred_enqueue() was continuing to operate on an skb it no longer owns in this\ncase -- enqueueing it, dropping it, or updating statistics. Resulting in a UAF.\n\n tc qdisc add dev eth0 root handle 1: red ... qevent early_drop block 10\n tc filter add block 10 ... action ct\n\n (with ct defrag enabled and traffic that produces out-of-order\n fragments, e.g. a fragmented UDP stream)\n\nHandle TC_ACT_CONSUMED in tcf_qevent_handle() the same way the ingress\nand egress fast paths do: treat it as stolen and return NULL without\ntouching the skb. Unlike the TC_ACT_STOLEN case, the skb must not be\ndropped/freed here, as it is no longer owned by us."

No local netlink access is required to trigger the deployed configuration.\nAC:L - The attacker controls fragment contents and ordering and can drive RED into deterministic hard-mark or drop conditions with sustained traffic. No race or condition outside the attacker\u0027s control must be won.\nPR:N - CAP_NET_ADMIN is required to create the vulnerable configuration, but a remote attacker sending fragments through an already configured appliance needs no privileges or authentication. Local triggering is also possible with namespaced CAP_NET_ADMIN.\nUI:N - Triggering requires only attacker-generated fragmented traffic and does not depend on a victim performing any action.\nS:U - The corruption occurs within the host kernel and compromises resources governed by that same security authority. This remains unchanged scope even when used for namespace escape or kernel privilege escalation.\nC:H - The reclaimable sk_buff use-after-free and corrupted defragmentation-tree links can be leveraged through attacker-controlled network heap spraying to disclose arbitrary kernel memory.\nI:H - RED overwrites linkage fields that overlap the defragmentation RB node and may free the object while it remains referenced, enabling subsequent writes through freed or attacker-reclaimed kernel objects and potential code execution.\nA:H - The dangling fragment-tree entry can cause immediate or deferred use-after-free, double-free, invalid tree operations, and kernel panic when another fragment arrives or the queue expires. The attacker can trigger this repeatedly with fragmented traffic."
