UBUNTU-CVE-2025-68784
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.
