[PATCH openEuler-1.0-LTS] f2fs: explicitly null-terminate the xattr list
by Zizhi Wo 22 Feb '24

22 Feb '24

From: Eric Biggers <ebiggers(a)google.com> mainline inclusion from mainline-v6.8-rc1 commit e26b6d39270f5eab0087453d9b544189a38c8564 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I92HXK CVE: CVE-2023-52436 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- When setting an xattr, explicitly null-terminate the xattr list. This eliminates the fragile assumption that the unused xattr space is always zeroed.
