In the Linux kernel, the following vulnerability has been resolved: l2tp: fix tunnel and session refcount leak on seqfile release In pppol2tpprocopen and l2tpdfsseqopen, iteration state pd-tunnel and pd-session is kept in seqfile private data to allow iteration across multiple read system calls...

CVE-2026-74748

CVE-2026-74748 is a refcount race in the Linux kernel's netfilter ipset subsystem. The function __ip_set_put_byindex() resolves a set index under RCU but decrements the reference count only after acquiring ip_set_ref_lock. A concurrent ip_set_swap() call can interleave between these two steps, ca...
