btrfs: fix use-after-free when attempting to join an aborted transaction
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix use-after-free when attempting to join an aborted transaction
When we are trying to join the current transaction and if it's aborted,
we read its 'aborted' field after unlocking fs_info->trans_lock and
without holding any extra reference count on it. This means that a
concurrent task that is aborting the transaction may free the transaction
before we read its 'aborted' field, leading to a use-after-free.
Fix this by reading the 'aborted' field while holding fs_info->trans_lock
since any freeing task must first acquire that lock and set
fs_info->running_transaction to NULL before freeing the transaction.
This was reported by syzbot and Dmitry with the following stack traces
from KASAN:

The window is further widened because __btrfs_abort_transaction sets transaction-\u003eaborted and then emits a WARN stack dump and printk before setting fs_info-\u003efs_error (the gate that would short-circuit join_transaction), and in the -EROFS/read-only case fs_error is never set at all.\nPR:L - Any unprivileged local user with write access to a btrfs filesystem can reach both sides: 53 btrfs_abort_transaction() call sites in fs/btrfs/inode.c alone fire on unprivileged create/unlink/rename/truncate paths (name hash collisions, ENOSPC, item overflow), and join_transaction is hit by every file operation. No capability, ioctl privilege, or namespace trickery is needed.\nUI:N - btrfs is the default root filesystem on Fedora, openSUSE, Synology NAS and many Android devices, so the volume is already mounted and the attacker needs no victim to mount an image or open a file. The entire sequence runs from the attacker\u0027s own threads.\nS:U - The use-after-free corrupts kernel heap state within the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The 4-byte read of freed kmalloc-2k memory is propagated out of start_transaction() as the syscall error code, directly leaking heap contents to userspace, and the resulting wild ERR_PTR / refcount-imbalanced transaction join gives an attacker who sprays the freed slab a path to arbitrary kernel reads.\nI:H - A groomed value below -MAX_ERRNO defeats IS_ERR(), so callers dereference an attacker-influenced 0xffffffffxxxxxxxx pointer as a struct btrfs_trans_handle and write through it into the kernel text/module region; a non-negative value instead joins a transaction without incrementing use_count/num_writers, yielding a refcount underflow and a full write-capable UAF.\nA:H - This is a KASAN-confirmed slab use-after-free; a non-negative stale value sends start_transaction into cur_trans-\u003etransid with fs_info-\u003erunning_transaction already NULLed, producing an immediate NULL pointer dereference and kernel oops."

Title
ipv6: mcast: add RCU protection to mld_newpack()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: mcast: add RCU protection to mld_newpack()
mld_newpack() can be called without RTNL or RCU being held.
Note that we no longer can use sock_alloc_send_skb() because
ipv6.igmp_sk uses GFP_KERNEL allocations which can sleep.
Instead use alloc_skb() and charge the net->ipv6.igmp_sk
socket under RCU protection.

This matches the AV:N assessment of its direct IPv4 counterpart `arp_xmit()` in the same series.\nAC:H - The stale `struct net` only becomes a use-after-free if the device\u0027s netns is concurrently dismantled (`dev_change_net_namespace()` from `default_device_exit_batch()` followed by `net_free()`), and a remote attacker can neither trigger nor time netns teardown. Hitting the window therefore depends on host-side container/netns churn outside the attacker\u0027s control.\nPR:N - The ND transmit path is entered from unauthenticated received packets and from routing-driven neighbour probing; no credentials, account, or capability on the target host are needed to drive it.\nUI:N - Neighbour solicitation, router probing and NA replies are automatic kernel behaviours triggered by packet arrival and timer/workqueue expiry; no victim action is involved.\nS:U - The freed `struct net`, its `ndisc_sk`, MIB counters and netfilter hook arrays all live in the kernel\u0027s own security authority, so impact stays within the kernel \u2014 no VM, IOMMU or sandbox boundary is crossed.\nC:H - `sk` is loaded from the freed `net`, and `READ_ONCE(inet6_sk(sk)-\u003ehop_limit)` is copied into a transmitted ICMPv6 header, so a reclaimed-slab spray yields a read of attacker-chosen kernel memory exfiltrated onto the wire; more generally a UAF of `struct net` gives an arbitrary-read primitive.\nI:H - `IP6_INC_STATS`/`ICMP6_INC_STATS` increment through a per-cpu pointer read from freed memory, and `NF_HOOK()` dispatches indirect calls through `net-\u003enf.hooks_ipv6[]` loaded from the freed object, giving both a write primitive and a plausible control-flow-hijack path.\nA:H - Dereferencing a freed `struct net` and the garbage `ndisc_sk` pointer derived from it reliably produces an oops or panic, and the corrupted netfilter hook walk can take the whole kernel down."

The vulnerable code is bound to the network stack and reachable from remotely originated packets, so Network is the correct and higher-severity classification.\nAC:H - The attacker fully controls and can sustain the ARP-transmit side of the race, but the other side \u2014 a `struct net` being freed via `cleanup_net()` or a device migrating namespaces \u2014 is background system activity the network attacker cannot command. Because that condition lies outside attacker control, complexity is High.\nPR:N - There is no capability check, credential check, or authentication gate anywhere on the path from packet receipt/neighbour resolution to `arp_xmit()`; ARP solicitation and reply generation happen unconditionally in softirq context. An entirely unauthenticated attacker reaches the vulnerable code.\nUI:N - The attacker\u0027s own packets cause the kernel to emit ARP and execute the vulnerable code; no victim must mount a filesystem, open a file, or take any other action.\nS:U - The use-after-free of `struct net` and the resulting corruption stay entirely within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free of `struct net` lets `nf_hook()` read `net-\u003enf.hooks_arp[]` and every ARP-family hook read `state-\u003enet` out of freed, potentially reallocated slab memory. Per kernel guidance a UAF gives the attacker control over the freed object\u0027s contents and thus an arbitrary kernel-memory read primitive.\nI:H - The stale `net` yields a `hook_head` pointer from freed memory, and `nf_hook_slow()` then performs an indirect call through `e-\u003ehooks[s].hook` \u2014 a direct function-pointer hijack primitive if the netns slab is reallocated with sprayed data. Hooks also write through `state-\u003enet`, corrupting reused kernel objects.\nA:H - Dereferencing a freed `struct net` and calling through a garbage `nf_hook_entries` reliably oopses or panics the kernel, and is a KASAN-reportable memory-safety violation that panics on hardened configurations. Any such kernel crash is scored High."

A purely remote or adjacent peer can generate ARP/NDISC traffic to reach `__neigh_notify()` but cannot cause the namespace pointer to go stale.\nAC:L - The attacker controls both sides: they spin a loop creating/destroying network namespaces with veth devices while concurrently driving neighbour add/update/GC notifications on other CPUs, so the race is created rather than waited for. Per race-condition guidance, attacker-created races are Low even though the window between the `dev_net()` load and the `net-\u003ertnl` dereference is narrow.\nPR:L - `unshare -Urn` grants namespace-relative CAP_NET_ADMIN (`ns_capable(net-\u003euser_ns, CAP_NET_ADMIN)`), letting an ordinary unprivileged user create netns, create and move veth pairs, and trigger the teardown path; no real root is needed. Neighbour-table activity that reaches `__neigh_notify()` is likewise available to any unprivileged process.\nUI:N - The attacker triggers both the namespace teardown and the neighbour notifications entirely from their own processes. No victim action, mount, or file open is involved.\nS:U - The use-after-free and its consequences are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed. This is standard in-kernel corruption leading to local privilege escalation.\nC:H - The freed `struct net` is a reclaimable `net_cachep` slab object, and `net-\u003ertnl` is subsequently consumed as a `struct sock *` by `netlink_set_err()`/`nlmsg_notify()`, which read `sk-\u003esk_protocol` and `sock_net(sk)` and walk netlink tables from it. Heap-spraying the freed object turns this into an attacker-directed kernel read primitive.\nI:H - With the freed `struct net` reclaimed under attacker control, `netlink_set_err()` writes through the forged `sk` pointer (`sk-\u003esk_err = err`, list/waitqueue manipulation), giving a controlled kernel write usable for control-flow hijacking. Per guidance, use-after-free is scored High for integrity.\nA:H - Even without successful reclaim, dereferencing the freed `struct net` and the dangling `net-\u003ertnl` socket causes a kernel oops or panic in `nlmsg_notify()`/`netlink_set_err()`. The trigger loop can be repeated indefinitely by an unprivileged user."

Title
clocksource: Use migrate_disable() to avoid calling get_random_u32() in atomic context
Summary
In the Linux kernel, the following vulnerability has been resolved:
clocksource: Use migrate_disable() to avoid calling get_random_u32() in atomic context
The following bug report happened with a PREEMPT_RT kernel:
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2012, name: kwatchdog
preempt_count: 1, expected: 0
RCU nest depth: 0, expected: 0
get_random_u32+0x4f/0x110
clocksource_verify_choose_cpus+0xab/0x1a0
clocksource_verify_percpu.part.0+0x6b/0x330
clocksource_watchdog_kthread+0x193/0x1a0
It is due to the fact that clocksource_verify_choose_cpus() is invoked with
preemption disabled. This function invokes get_random_u32() to obtain
random numbers for choosing CPUs. The batched_entropy_32 local lock and/or
the base_crng.lock spinlock in driver/char/random.c will be acquired during
the call. In PREEMPT_RT kernel, they are both sleeping locks and so cannot
be acquired in atomic context.
Fix this problem by using migrate_disable() to allow smp_processor_id() to
be reliably used without introducing atomic context. preempt_disable() is
then called after clocksource_verify_choose_cpus() but before the
clocksource measurement is being run to avoid introducing unexpected
latency.
Severity
No CVSS data available.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nclocksource: Use migrate_disable() to avoid calling get_random_u32() in atomic context\n\nThe following bug report happened with a PREEMPT_RT kernel:\n\n BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48\n in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2012, name: kwatchdog\n preempt_count: 1, expected: 0\n RCU nest depth: 0, expected: 0\n get_random_u32+0x4f/0x110\n clocksource_verify_choose_cpus+0xab/0x1a0\n clocksource_verify_percpu.part.0+0x6b/0x330\n clocksource_watchdog_kthread+0x193/0x1a0\n\nIt is due to the fact that clocksource_verify_choose_cpus() is invoked with\npreemption disabled. This function invokes get_random_u32() to obtain\nrandom numbers for choosing CPUs. The batched_entropy_32 local lock and/or\nthe base_crng.lock spinlock in driver/char/random.c will be acquired during\nthe call. In PREEMPT_RT kernel, they are both sleeping locks and so cannot\nbe acquired in atomic context.\n\nFix this problem by using migrate_disable() to allow smp_processor_id() to\nbe reliably used without introducing atomic context. preempt_disable() is\nthen called after clocksource_verify_choose_cpus() but before the\nclocksource measurement is being run to avoid introducing unexpected\nlatency."
