CVE-2026-89570

A flaw was found in the Linux kernel's Compute Express Link CXL subsystem. Lifetime issues with the CXL Machine Check Exception MCE notifier can lead to NULL dereferences and use-after-free vulnerabilities in the MCE handler. This could allow an attacker to cause system instability or a denial of...

CVE-2026-89662

A flaw was found in the Linux kernel's Network File System Daemon NFSD. During client teardown, a race condition can occur where a lock owner is freed while still being referenced, leading to a use-after-free vulnerability. This can result in a NULL dereference, potentially causing a system crash...

CVE-2026-89517

A flaw was found in the Linux kernel's schedext component, which handles core scheduling. When multiple selections on the same core interleave due to a dropped lock, they can corrupt the scheduling state. This corruption can lead to a NULL dereference, tasks remaining active after being dequeued,...

CVE-2026-89679

A flaw was found in the Linux kernel's nfsd component. A remote attacker can exploit this by sending a specially crafted SETATTR request that includes specific delegation timestamp attributes and a special NFSv4 state ID. This triggers a null dereference, leading to a kernel crash and a Denial of...
