Astra Linux – Vulnerability in Linux 5.10, Linux
In the Linux kernel, the following vulnerability has been resolved: perf/core: Fixed a data race between perfeventsetoutput and perfmmapclose. Yang Jihing reported a race between perfeventsetoutput and perfmmapclose: CPU1 CPU2 perfmmapclosee2 if atomicdecandtest&e2-rb-mmapcount // 1 - 0 then...
The vulnerability of the `tracing_buffers_mmap_close()` function in the kernel/trace/trace.c module, which supports Linux operating system’s kernel tracing functionality, allows a hacker to cause a service failure.
The vulnerability of the tracingbuffersmmapclose function in the kernel/trace/trace.c module, which supports Linux operating system’s kernel tracing mechanism, involves copying buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability can...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: perf/core: The handling of buffer mapping fails correctly in perfmmap. After a buffer is successfully allocated or attached to an existing buffer, perfmmap attempts to map the buffer into the page table in read-only mode. If this...
SUSE CVE-2026-23380
In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose When a process forks, the child process copies the parent's VMAs but the usermapped reference count is not incremented. As a result, when both the parent and child processes exit,...
CVE-2026-23380
CVE-2026-23380 (Linux kernel) describes a local vulnerability in tracing buffers memory management. When a process forks, the child’s VMAs copy the parent’s without incrementing user_mapped, so exiting both processes may cause tracing_buffers_mmap_close() to run twice; on the second call user_map...

SUSE CVE-2025-68329
In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose for split VMAs When a VMA is split e.g., by partial munmap or MAPFIXED, the kernel calls vmops-close on each portion. For trace buffer mappings, this results in ringbufferunmap being...

DEBIAN-CVE-2025-38565
In the Linux kernel, the following vulnerability has been resolved: perf/core: Exit early on perfmmap fail When perfmmap fails to allocate a buffer, it still invokes the eventmapped callback of the related event. On X86 this might increase the perfrdpmcallowed reference counter. But nothing undoe...

CVE-2022-49607
CVE-2022-49607 concerns a data race in the Linux kernel between perf_event_set_output() and perf_mmap_close() in the perf/core subsystem. The root cause is a race where perf_mmap_close() holds e2->mmap_mutex while perf_event_set_output() holds e1->mmap_mutex, allowing no serialization and p...
