CVE-2023-53718 ring-buffer: Do not swap cpu_buffer during resize process

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-2023-53718

CVE-2023-53718 affects the Linux kernel ring-buffer code. The issue occurs when ring_buffer_swap_cpu is called during a resize, causing the cpu_buffer to be swapped mid‑operation and leaving the ring buffer in an inconsistent state that can lead to an oops. Reproduction in the initial document sh...

CVE-2023-53709

CVE-2023-53709 affects the Linux kernel ring-buffer subsystem. The vulnerability arises from a race between rb_move_tail and rb_check_pages where RB_FLAG on head_page is updated during an integrity check and then cleared, creating a data race that can corrupt the ring buffer’s integrity. The issu...

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...
