CVE-2026-43210

The CVE-2026-43210 entry concerns the Linux kernel tracing ring-buffer subsystem. The root cause is inadequate validation of event length in rb_read_data_buffer(), which can cause an invalid memory access if an event’s length is corrupted, potentially at boot time. The published fix is to check t...

CVE-2026-43210 tracing: ring-buffer: Fix to check event length before using

In the Linux kernel, the following vulnerability has been resolved: tracing: ring-buffer: Fix to check event length before using Check the event length before adding it for accessing next index in rbreaddatabuffer. Since this function is used for validating possibly broken ring buffers, the lengt...

CVE-2026-43121

CVE-2026-43121 involves the Linux kernel io_uring/zcrx race between scrub and refill paths. The non-atomic read-then-decrement of the user_refs can race with io_zcrx_scrub() using atomic_xchg, causing a double-free of a niov and an out-of-bounds write past the freelist array. The fix replaces the...

CVE-2026-31700

A flaw was found in the Linux kernel. A Time-of-check to Time-of-use TOCTOU race condition exists in the tpacketsnd function when PACKETVNETHDR is enabled. A local user can exploit this by modifying the vnethdr fields in the mmap'd TX ring buffer between validation and use, thereby bypassing safe...
