CVE-2026-80551

A flaw was found in the Linux kernel's s390/vfioccw component. This vulnerability arises because the system does not ensure that the address in the first Indirect Data Address Word IDAW remains constant between reads. An attacker could potentially exploit this to cause the system to operate with ...

EUVD-2026-66466

In the Linux kernel, the following vulnerability has been resolved: s390/vfioccw: Ensure first IDAW remains constant The first IDAW in a list does not need to be on a 2K/4K boundary like all others, and so is read separately to accurately calculate the size of the buffer needed to read the full...

CVE-2026-80551

CVE-2026-80551 affects the s390/vfio_ccw subsystem in the Linux kernel. The vulnerability stems from the first IDAW in a list being read separately (since it does not require 2K/4K alignment like subsequent entries) to calculate the buffer size for reading the full IDAL. The fix verifies that the...

CVE-2024-42099

The CVE-2024-42099 issue affects the Linux kernel on s390/dasd, where an invalid dereferencing of the indirect CCW data pointer (IDAW) could trigger a kernel panic in error paths. The root cause is that the CCW CDA pointer points to the IDAL, not directly to the data address, requiring translatio...
