cve-2023-1583 Vulnerabilidad documentada
N/A
A NULL pointer dereference was found in io_file_bitmap_get io_uring/filetable.c the io_uring sub-component Linux Kernel. When fixed files are unregistered, some context information (file_alloc_{start,end} and alloc_hint) is not cleared. A subsequent request that has auto index selection enabled via IORING_FILE_INDEX_ALLOC can cause a dereference. An unprivileged user use flaw to system crash.
