CVE-2023-54139

CVE-2023-54139: In the Linux kernel, the tracing/user_events path was fixed to ensure the write index used for per-file event data cannot be negative. The vulnerability could allow out-of-bounds access if a signed index is provided via write() (first 4 bytes). The fix returns -EINVAL to reject ne...

CVE-2025-68329

The CVE-2025-68329 entry documents a Linux kernel issue in tracing: when a VMA is split, the kernel could invoke ring_buffer_unmap multiple times (due to multiple vm_ops->close calls) while ring_buffer_map was called once, causing ring_buffer_unmap to return -ENODEV and triggering a WARN_ON. T...
