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 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...

In the Linux kernel, the following vulnerabilities have been resolved: Ring-Buffer: Fixed a deadloop issue when reading tracepipe. A soft lockup occurs when reading the file ‘tracepipe’: - Watchdog: BUG: Soft lockup – CPU6 stuck for 22 seconds! cat:4488 - ... - RIP: 0010:...
Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1
In the Linux kernel, the following vulnerability has been resolved: Ring-buffer: Do not attempt to read beyond the “commit” boundary. When iterating over the ring buffer while the ring buffer is active, the writer can corrupt the reader’s data. There are mechanisms to detect and handle this issue...

In the Linux kernel, the following vulnerability has been resolved: Ring-buffer: Fixed a race condition between readers and resize checks. The reader code in rbgetreaderpage swaps a new reader page into the ring buffer by using cmpxchg on old-list.prev-next to point it to the new page. After that...
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 found in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: Ring-Buffer: Handled race conditions between rbmovetail and rbcheckpages. It appears there is a data race between writing to the ringbuffer and performing integrity checks. Specifically, the RBFLAG of headpage is being updated,...
