CVE-2026-31642

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix call removal to use RCU safe deletion Fix rxrpc call removal from the rxnet-calls list to use listdelrcu rather than listdelinit to prevent stuffing up reading /proc/net/rxrpc/calls from potentially getting into an...

CVE-2026-31642

The CVE-2026-31642 entry concerns the Linux kernel rxrpc module, where a flaw in call removal was fixed by using list_del_rcu() instead of list_del_init() to prevent infinite loops when reading /proc/net/rxrpc/calls. The underlying issue is that improperly deleting calls could disrupt list handli...
