kernel: mm/slub: Avoid list corruption when removing a slab from the full list

A use-after-free list corruption vulnerability was found in the Linux kernel. If an allocated object fails in allocconsistencychecks, all objects of the slab will be marked as used and the slab will be removed from the partial list. When an object belonging to the slab gets freed later, the...

xorg: xwayland: Use of uninitialized pointer in compRedirectWindow()

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow will return a BadAlloc error without validating the window tree marked just before, which leaves the...
