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-2026-80555 s390/vfio_ccw: Free all memory if cp_init() fails

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...

CVE-2026-80554 s390/vfio_ccw: Limit the number of channel program segments

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-2026-74736

CVE-2026-74736 is a Linux kernel vulnerability in the net/sched cls_bpf classifier. The function cls_bpf_prog_from_efd() retrieved a SCHED_CLS program via bpf_prog_get_type_dev() without verifying that a device-bound (offloaded) BPF program's bound netdev matched the target TC netdev. This allowe...
