In the Linux kernel, the following vulnerability has been resolved:
afs: Fix afseditdirremove() to get, not find, block 0
Fix afseditdirremove() to use afsdirgetblock() to get block 0 rather than afsdirfindblock() as the latter caches the found block in the afsdiriter and may[] switch out the page it's on if another afsdirfindblock() is done. This parallels what afseditdiradd() does.
[] There's more than one block per page.
