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...
