CVE-2024-26694

Severity CVSS v4.0:
Pending analysis
Type:
CWE-415 Double Free
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: iwlwifi: fix double-free bug<br /> <br /> The storage for the TLV PC register data wasn&amp;#39;t done like all<br /> the other storage in the drv-&gt;fw area, which is cleared at the<br /> end of deallocation. Therefore, the freeing must also be done<br /> differently, explicitly NULL&amp;#39;ing it out after the free, since<br /> otherwise there&amp;#39;s a nasty double-free bug here if a file fails<br /> to load after this has been parsed, and we get another free<br /> later (e.g. because no other file exists.) Fix that by adding<br /> the missing NULL assignment.
