CVE-2026-23004

The CVE-2026-23004 issue in the Linux kernel concerns races in the IPv6 dst cache path (rt6_uncached_list_del/rt_del_uncached_list) leading to use-after-free during list_head initialization in INIT_LIST_HEAD, as observed by KASAN in rt6_uncached_list_flush_dev and related paths. The root cause is...

USN-5941-1 linux-kvm vulnerabilities

It was discovered that the Upper Level Protocol ULP subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execut...
