Vulnerability from github – Published: 2026-08-10 15:33 – Updated: 2026-08-10 15:33

Details

In the Linux kernel, the following vulnerability has been resolved:

afs: Fix afs_edit_dir_remove() to get, not find, block 0

Fix afs_edit_dir_remove() to use afs_dir_get_block() to get block 0 rather than afs_dir_find_block() as the latter caches the found block in the afs_dir_iter and may[*] switch out the page it's on if another afs_dir_find_block() is done. This parallels what afs_edit_dir_add() does.

[*] There's more than one block per page.
