| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.1.0-060100rc3-generic
Description
The issue is related to a possible out-of-bound access in the
ieee80211 get rate duration routine. This was reported by a UBSAN (Undefined Behavior Sanitizer) report, which indicated an array-index-out-of-bounds error in the net/mac80211/airtime.c file. The error occurred because an index of 15 was out of range for a type 'u16 [12]'. The vulnerability is related to the wifi and mac8021 components of the Linux kernel.Recommendations
For Linux kernel versions prior to 6.1.0-060100rc3-generic, consider updating to a newer version that includes the fix for the out-of-bound access issue in the
ieee80211 get rate duration routine. As a temporary workaround, consider restricting access to the vulnerable wifi and mac8021 components until a patch is available.Exploit
