发布于3月6日3月6日 Members Huawei EulerOS: CVE-2024-39482: kernel security update Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 07/05/2024 Created 10/10/2024 Added 10/09/2024 Modified 01/30/2025 Description In the Linux kernel, the following vulnerability has been resolved: bcache: fix variable length array abuse in btree_iter btree_iter is used in two ways: either allocated on the stack with a fixed size MAX_BSETS, or from a mempool with a dynamic size based on the specific cache set. Previously, the struct had a fixed-length array of size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized iterators, which causes UBSAN to complain. This patch uses the same approach as in bcachefs's sort_iter and splits the iterator into a btree_iter with a flexible array member and a btree_iter_stack which embeds a btree_iter as well as a fixed-length data array.
