CVE-2026-53144

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix NULL dereference in getqueueids When usrqueueidarray is NULL and numqueues is non-zero, getqueueids returns NULL. The callers check only ISERR on the return value; since ISERRNULL == false the check passes, and...

CVE-2026-53219

The CVE-2026-53219 issue affects the Linux kernel netfilter x_tables path. The root cause is that native/compat get-entries copied the fixed rule entry header to userspace before sanitizing and overwriting the counter fields, exposing the percpu allocation address (pcnt) in SMP environments. The ...
