7.8 · HIGH
Published Apr 17, 2024 linux CWE-416 EPSS 0.23% (14th pctl)

Overview

CVE-2024-26892 is a high-severity vulnerability affecting linux linux_kernel. It was published on April 17, 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: mt76: mt7921e: fix use-after-free in free_irq()

From commit a304e1b82808 ("[PATCH] Debug shared irqs"), there is a test

to make sure the shared irq handler should be able to handle the unexpected

event after deregistration. For this case, let's apply MT76_REMOVED flag to

indicate the device was removed and do not run into the resource access

anymore.
