CVE-2024-56609

7.8 · HIGH
Published Dec 27, 2024 linux EPSS 0.23% (13th pctl)

Overview

CVE-2024-56609 is a high-severity vulnerability affecting linux linux_kernel. It was published on December 27, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

wifi: rtw88: use ieee80211_purge_tx_queue() to purge TX skb

When removing kernel modules by:

rmmod rtw88_8723cs rtw88_8703b rtw88_8723x rtw88_sdio rtw88_core

Driver uses skb_queue_purge() to purge TX skb, but not report tx status

causing "Have pending ack frames!" warning. Use ieee80211_purge_tx_queue()

to correct this.

Since ieee80211_purge_tx_queue() doesn't take locks, to prevent racing

between TX work and purge TX queue, flush and destroy TX work in advance.
