EUVD-2026-66469

In the Linux kernel, the following vulnerability has been resolved: s390/vfioccw: Limit the number of channel program segments The processing of channel programs, and the CCWs within them, is done recursively. As such, there is an arbitrary but not architectural limit to the number of CCWs that c...

CVE-2026-80554

A flaw was found in the Linux kernel's s390/vfioccw component. The vfio-ccw logic processes channel programs recursively, breaking them into segments when a Transfer-In-Channel TIC Channel Command Word CCW is encountered. An attacker could exploit the lack of a proper limit on these segments,...

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 ...

CVE-2026-80551 s390/vfio_ccw: Ensure first IDAW remains constant

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...

UBUNTU-CVE-2022-50307

In the Linux kernel, the following vulnerability has been resolved: s390/cio: fix out-of-bounds access on cioignore free The channel-subsystem-driver scans for newly available devices whenever device-IDs are removed from the cioignore list using a command such as: echo free /proc/cioignore Since ...
