PT-2025-43119

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.5.0-rc1-00276-g20edcec23f92 Description A flaw exists in the Linux kernel related to the ring buffer implementation. Specifically, the cpu buffer can be swapped during a resize process, leading to an incorrect...

GHSA-FP5X-7M4Q-449F Direct Ring Buffer has uninitialized memory exposure in create_ring_buffer

The safe function createringbuffer allocates a buffer using Vec::withcapacity followed by setlen, creating a Box containing uninitialized memory. This leads to undefined behavior when functions like writeslices create typed slices e.g., &mut bool over the uninitialized memory, violating Rust's...

CVE-2023-53668

CVE-2023-53668 affects the Linux kernel ring-buffer subsystem used by tracing_read_pipe/trace_pipe. The issue is a deadloop where a non-empty buffer cannot be read because rb_num_of_entries() == 0, leading to endless waiting when user-space buffers aren’t filled. Root cause: when the ringbuffer i...
