CVE-2026-80710 s390/dasd: Fix undersized format-check buffer

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: Fix undersized format-check buffer fmtbuffersize in dasdeckdcheckdeviceformat is declared as int, even though one of the multiplicands, sizeofstruct eckdcount, is a sizet. The expression trkcount rptmax sizeofstruct...

CVE-2026-74736

A flaw was found in the Linux kernel's clsbpf component. A device-bound program could be incorrectly attached to a different network device than it was intended for. This misconfiguration could allow an attacker to trigger a system panic, leading to a denial of service, if the original device is...

CVE-2026-80555

CVE-2026-80555 affects the Linux kernel on s390 architecture, specifically the vfio_ccw subsystem. The root cause is a memory leak that occurs when cp_init() fails: the existing cleanup in ccwchain_handle_ccw() only frees the currently-processed CCW segment, leaking other segments allocated as pa...

CVE-2026-80554

CVE-2026-80554 affects the Linux kernel's s390/vfio_ccw subsystem. The root cause is the recursive processing of channel programs: the vfio-ccw logic splits channel programs into segments at each Transfer-In-Channel (TIC) CCW , and the combined segment count contributes to a global limit on CCWs ...
