Vulnerability from github – Published: 2024-04-03 15:30 – Updated: 2025-01-07 21:30

Details

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.

Severity

7.8 (High)
