| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Linux kernel's wifi component, specifically the mac80211 module. A UBSAN warning occurs when the
ieee80211 get tx power() function returns the INT MIN value, which is used internally to represent an "unset power level". This warning is caused by a signed-integer-overflow in the net/wireless/nl80211.c file. The vulnerability may allow a remote attacker to access confidential data or cause a denial of service. The nl80211 send iface() function is involved in the call trace, and the ieee80211 if add() and ieee80211 register hw() functions are also mentioned.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
