Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: xsk: fix OOB map writes when deleting
elements Jordy says: " In the xsk_map_delete_elem function an unsigned integer (map->max_entries) is
compared with a user-controlled signed integer (k). Due to implicit type conversion, a large unsigned
value for map->max_entries can bypass the intended bounds check: if (k >= map->max_entries) return
-EINVAL; This allows k to hold a negative value (between -2147483648 and -2), which is then used as an
array index in m->xsk_map[k], which results in an out-of-bounds access. spin_lock_bh(&m->lock); map_entry
= &m->xsk_map[k]; // Out-of-bounds map_entry old_xs = unrcu_pointer(xchg(map_entry, NULL)); // Oob write
if (old_xs) xsk_map_sock_delete(old_xs, map_entry); spin_unlock_bh(&m->lock); The xchg operation can then
be used to cause an out-of-bounds write. Moreover, the invalid map_entry passed to xsk_map_sock_delete can
lead to further memory corruption. " It indeed results in following splat: [76612.897343] BUG: unable to
