Technical description
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.
