**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.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability in the Linux kernel has been resolved. The issue is related to the rtw89 driver, where hardware reports an incorrect mac id, leading to memory pollution. The problem occurs when the index is not checked before accessing an array, resulting in an out-of-bounds error. This error is identified by the UBSAN (Undefined Behavior Sanitizer) as an array-index-out-of-bounds in the rtw89/phy.c file. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
