CVE-2026-45995

A flaw was found in the Linux kernel's iouring/zcrx subsystem. This use-after-free UAF vulnerability occurs because the iofreerbufring function uses a struct userstruct that is prematurely freed by iozcrxifqfree before the ring is destroyed. A local attacker could potentially exploit this flaw to...

CVE-2026-45995

The CVE-2026-45995 entry concerns the Linux kernel io_uring subsystem. A use-after-free (UAF) was fixed where io_free_rbuf_ring() used a struct user_struct and io_zcrx_ifq_free() released it before destroying the ring. The patch resolves the UAF by ensuring correct lifetime management of the user...
