CVE-2024-26693

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A DoS tool that injects loads of authentication frames can cause the AP to crash. The iwl mvm is dup() function couldn't find the per-queue dup data which was not allocated. The root cause is that the firmware ran out of stations and didn't return an error to mac80211. This allowed ieee80211 find sta by ifaddr() to return a valid station object, but the ieee80211 sta didn't have any iwl mvm sta object initialized, causing a crash when receiving data on that station.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
