In the Linux kernel, the following vulnerability has been resolved: xsk: fix NULL pointer dereference in xskrcv In the xskrcv multi-buffer path, xskbuffalloc is called in a loop without checking its return value. xskbuffcanalloc only counts fill queue entries without validating their addresses, s...

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-2026-90102

CVE-2026-90102 is a Linux kernel vulnerability in the NFSv4/pnfs flexfiles layout driver. The per-net data server cache in nfs4_pnfs_ds_add() keyed entries only on the multipath address set, ignoring the NFS version. When one address legitimately serves both NFSv3 and NFSv4 , two deviceids alias ...

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...
