In the Linux kernel, the following vulnerability has been resolved: dst: fix races in rt6uncachedlistdel and rtdeluncachedlist syzbot was able to crash the kernel in rt6uncachedlistflushdev in an interesting way 1 Crash happens in listdelinit/INITLISTHEAD while writing list-prev, while the prior...

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...
