CVE-2024-26694

CVE-2024-26694 is a high-severity vulnerability in Linux Linux Kernel with a CVSS 3.x base score of 7.8. It is not currently listed as actively exploited by CISA, and its EPSS exploit-prediction score is low. The underlying weakness is classified as CWE-415.

Key facts

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: fix double-free bug The storage for the TLV PC register data wasn't done like all the other storage in the drv->fw area, which is cleared at the end of deallocation. Therefore, the freeing must also be done differently, explicitly NULL'ing it out after the free, since otherwise there's a nasty double-free bug here if a file fails to load after this has been parsed, and we get another free later (e.g. because no other file exists.) Fix that by adding the missing NULL assignment.
