CVE-2025-68784 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
xfs: fix a UAF problem in xattr repair
The xchk_setup_xattr_buf function can allocate a new value buffer, which means that any reference to ab->value before the call could become a dangling pointer. Fix this by moving an assignment to after the buffer setup.
