GHSA-X5XP-6CPR-4XWX

Vulnerability from github – Published: 2023-07-21 21:30 – Updated: 2024-08-22 21:31

Details

An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation.

The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks.

We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.

Severity ?

7.8 (High)


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