发布于3月6日3月6日 Members Debian: CVE-2023-1583: linux -- security update Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 03/24/2023 Created 07/31/2024 Added 07/30/2024 Modified 01/28/2025 Description A NULL pointer dereference was found in io_file_bitmap_get in io_uring/filetable.c in the io_uring sub-component in the 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 NULL pointer dereference. An unprivileged user can use the flaw to cause a system crash.
