CVE-2026-46136

CVE-2026-46136 affects the Linux kernel wifi driver mt7921 (mt76) where a buf_len underflow in the country power setting retrieval can occur after changes to the CLC power table. This underflow may cause an almost infinite loop or an invalid power setting, leading to driver initialization failure...

xorg: xwayland: X.Org X server: Denial of Service via integer underflow in XKB compatibility map handling

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of servi...
