CVE-2026-52976

The CVE-2026-52976 issue affects the Linux kernel drm/xe driver. Two error-handling paths in xe_exec_queue_create_ioctl() can lead to memory corruption: (1) on xe_hw_engine_group_add_exec_queue() failure, the cleanup jumps to cleanup without xe_exec_queue_kill(), potentially leaving a queue in th...

CVE-2026-52932

A flaw was found in the Linux kernel's xfrm IPcomp IP Payload Compression Protocol component. This vulnerability involves improper memory deallocation during error handling, where allocated resources are not correctly freed. This could allow a local attacker to cause resource exhaustion,...

CVE-2026-52921

A flaw was found in the Linux kernel's netfilter ipset component. Specifically, certain hash set variants such as hash:ip,mark and hash:ip,port that iterate IPv4 ranges with a 32-bit iterator do not correctly stop at the end of the requested range. This can cause the iteration to advance beyond t...
