CVE-2024-42254

CVE-2024-42254 affects the Linux kernel io_uring subsystem. The issue stems from inconsistent NULL vs IS_ERR error handling in io_alloc_pbuf_ring(), leading to a KASAN null pointer dereference in __io_remove_buffers and related cleanup paths (/io_uring/kbuf.c and io_uring.c). The vulnerability wa...
