CVE-2026-72321

CVE-2026-72321 affects the Linux kernel’s IGMP timer handling (ipv4: igmp). The root cause is a memory leak when deleting or stopping timers in igmp_mod_timer() and igmp_stop_timer(): refcount_dec(&im->refcnt) can drop the group entry im to zero on an RC reader path, leaving the im object leak...

CVE-2026-72311

CVE-2026-72311 affects the Linux kernel DRM/XE path. The issue occurs in xe_vm_madvise_ioctl(), which allocates madvise_range.vmas in get_vmas(). When get_vmas() succeeds and later validation fails, control incorrectly jumps to madv_fini, skipping kfree(madvise_range.vmas) and leaking the VMA arr...
