Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Tracing: Free buffers when a used dynamic event is removed After 65536 dynamic events have been added and removed, the “type” field of the event uses the first available type number which is not currently used by other events. A...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: Ring Buffer: Do not swap the cpubuffer during the resize process When the ringbufferswapcpu function is called during the resize process, the cpu buffer is swapped in the middle, resulting in an incorrect state. Continuing to run...

Astra Linux – Vulnerability in Linux 5.10, Linux

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Ring Buffer: Check for NULL cpubuffer in ringbufferwakewaiters On some machines, the number of listed CPUs may be larger than the actual CPUs that exist. The tracing subsystem allocates a per-CPU directory with access to the...

kernel: ring-buffer: Do not trigger WARN_ON() due to a commit_overrun

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not trigger WARNON due to a commitoverrun When reading a memory mapped buffer the reader page is just swapped out with the last page written in the write buffer. If the reader page is the same as the commit buffer...

SUSE CVE-2026-43210

In the Linux kernel, the following vulnerability has been resolved: tracing: ring-buffer: Fix to check event length before using Check the event length before adding it for accessing next index in rbreaddatabuffer. Since this function is used for validating possibly broken ring buffers, the lengt...

CVE-2026-43272

A flaw was found in the Linux kernel's ring-buffer component. This vulnerability allows a local user to potentially cause a denial of service. The issue occurs because a pointer in the rbmetavalidateevents function is not properly initialized, and its dereference during a reader page validation...

Linux Distros Unpatched Vulnerability : CVE-2026-43210

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tracing: ring-buffer: Fix to check event length before using Check the event length before adding it for accessing next index in rbreaddatabuffer. Since this...

CVE-2026-43210

A flaw was found in the Linux kernel's tracing ring-buffer subsystem. This vulnerability occurs in the rbreaddatabuffer function, which fails to validate the length of an event before using it to determine the next memory address. If an event's length is corrupted, this can lead to an invalid...
