CVE-2026-64255

A flaw was found in the Linux kernel's iwlwifi Intel Wireless WiFi driver. This vulnerability allows an attacker to cause an out-of-bounds memory access in the WiFi Block Acknowledgement BA session handlers. This occurs when the stamask value is zero, leading to an incorrect station ID calculatio...

CVE-2026-64212

A flaw was found in the Linux kernel's iwlwifi driver. The iwlmldremovelink function does not properly check for a NULL pointer before dereferencing it. A local attacker could potentially exploit this null pointer dereference, leading to a system crash and a Denial of Service DoS...

UBUNTU-CVE-2026-64255

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: validate stamask before ffs in BA session handlers Three BA session handlers use ffsbadata-stamask - 1 to derive a station ID without checking that stamask is non-zero. When stamask is zero, ffs returns 0 and...
