EUVD-2026-81741

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Fix incorrect argument passed to nfs4deletelease in nfs4addlease When nfs4addlease races with a delegation return, it calls nfs4deletelease to clean up. Previously, it passed priv, which can legitimately be NULL. Passing a...

CVE-2026-90139

This vulnerability affects the Linux kernel FUSE (Filesystem in Userspace) module. The root cause is a NULL pointer dereference in fuse_fill_super_submount(): when fuse_iget() fails to allocate an inode (e.g., under memory pressure), the resulting NULL is passed unchecked to get_fuse_inode(), cau...

CVE-2026-90115

CVE-2026-90115 affects the Linux kernel XDP subsystem (net/xdp/xsk.c). In the __xsk_rcv() multi-buffer path, xsk_buff_alloc() is called in a loop without checking its return value. Since xsk_buff_can_alloc() only counts fill queue entries without validating their addresses, it can succeed while x...

CVE-2026-90091

CVE-2026-90091 is a race condition in the Linux kernel's Bluetooth L2CAP subsystem. For L2CAP sockets that do not own sk->sk_socket, an unsafe lockless read of l2cap_pi(sk)->chan in l2cap_sock_cleanup_listen() can race against a concurrent l2cap_sock_kill() → l2cap_sock_put_chan(), which se...

CVE-2026-90066

CVE-2026-90066 affects the Linux kernel 's samples/ftrace module (ftrace-direct-multi-modify). The root cause is a missing IS_ERR() check on the return value of kthread_run() in ftrace_direct_multi_init(). When kthread_run() fails (e.g., returning ERR_PTR(-ENOMEM)), the module loads with simple_t...
