EUVD-2026-66470

In the Linux kernel, the following vulnerability has been resolved: s390/vfioccw: Free all memory if cpinit fails The routine cpfree is called to unpin/free any memory once an I/O is completed successfully, or if cpprefetch fails. But if cpinit fails, and cp-initialized is not enabled, the same...

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-2026-80555

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 ...
