CVE-2023-54088

Estado: AplazadaAlta (7.8)—

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

blk-cgroup: hold queue_lock when removing blkg->q_node

When blkg is removed from q->blkg_list from blkg_free_workfn(), queue_lock has to be held, otherwise, all kinds of bugs(list corruption, hard lockup, ..) can be triggered from blkg_destroy_all().

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
