[PATCH OLK-5.10] iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihid

From: Pavel Paklov <Pavel.Paklov(a)cyberprotect.ru> stable inclusion from stable-v5.15.182 commit 466d9da267079a8d3b69fa72dfa3a732e1f6dbb5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC991Z CVE: CVE-2025-37927 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 8dee308e4c01dea48fc104d37f92d5b58c50b96c upstream. There is a string parsing logic error which can lead to an overflow of hid or uid buffers. Comparing ACPIID_LEN against a total string length doesn't take into account the lengths of individual hid and uid buffers so the check is insufficient in some cases. For example if the length of hid string is 4 and the length of the uid string is 260, the length of str will be equal to ACPIID_LEN + 1 but uid string will overflow uid buffer which size is 256. The same applies to the hid string with length 13 and uid string with length 250. Check the length of hid and uid strings separately to prevent buffer overflow.

[PATCH OLK-5.10] mm: proc: fix compile warning when CONFIG_NUMA=n
by Qi Xi 28 Nov '25

28 Nov '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID980J -------------------------------- Fix compile warning: 'numa_maps_next' defined but not used. The function use is controlled by CONFIG_NUMA, so its definition should be compiled under the same config option. Fixes: 094a76ab06c3 ("mm: proc: use per_vma mmap_lock for vma traversal.")
