7.0 · HIGH
Published May 1, 2024 linux CWE-416 EPSS 0.24% (15th pctl)

Overview

CVE-2024-26961 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 1, 2024 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, 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:

mac802154: fix llsec key resources release in mac802154_llsec_key_del

mac802154_llsec_key_del() can free resources of a key directly without

following the RCU rules for waiting before the end of a grace period. This

may lead to use-after-free in case llsec_lookup_key() is traversing the

list of keys in parallel with a key deletion:

refcount_t: addition on 0; use-after-free.
