In the Linux kernel, the following vulnerability has been resolved: btrfs: fix use-after-free when COWing tree bock and tracing is enabled When a COWing a tree block, at btrfscowblock, and we have the tracepoint tracebtrfscowblock enabled and preemption is also enabled CONFIGPREEMPT=y, we can...

CVE-2024-56759

CVE-2024-56759 concerns the Linux kernel: when Btrfs COWs a tree block with tracing enabled (trace_btrfs_cow_block) and preemption is on, a use-after-free can occur on the COWed extent buffer. The root cause is that tracepoint handling could observe a buffer after it is freed via RCUs, if preempt...
