Description OSIDB Bzimport 2026-01-13 16:04:36 UTC 
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.
