Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability that arises from failing to hold the cpubuffer::lock when adjusting the size of the subbuffer. This may lead to race conditions with the ringbufferallocreadpage and ringbufferfreereadpage functions...

CVE-2023-53718: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not swap cpubuffer during resize process When ringbufferswapcpu was called during resize process, the cpu buffer was swapped in the middle, resulting in incorrect state. Continuing to run in the wrong state will...

CVE-2023-53368: Concurrent Execution using Shared Resource with Improper Synchronization

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix race issue between cpu buffer write and swap Warning happened in rbendcommit at code: if RBWARNONcpubuffer, !localread&cpubuffer-committing WARNING: CPU: 0 PID: 139 at kernel/trace/ringbuffer.c:3142...

GSD-2022-1007974 ring-buffer: Check for NULL cpu_buffer in ring_buffer_wake_waiters()

ring-buffer: Check for NULL cpubuffer in ringbufferwakewaiters This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.15.78 by commit...
