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 xsk: fix NULL pointer dereference in __xsk_rcv()
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-2026-90091
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-2026-90091 Bluetooth: L2CAP: fix race l2cap_sock_cleanup_listen() vs. put_chan
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: fix race l2capsockcleanuplisten vs. putchan For L2CAP sockets without owning sk-sksocket, reading l2cappisk-chan may race against concurrent l2capsockkill - l2capsockputchan. This excludes simultaneous protoops...

In the Linux kernel, the following vulnerability has been resolved: samples/ftrace: Fix kthreadstop on ERRPTR in ftrace-direct-multi-modify ftracedirectmultiinit assigns kthreadrun's return value to simpletsk without an ISERR check. When kthreadrun fails it returns ERRPTR-ENOMEM, but init still...
CVE-2026-90066 samples/ftrace: Fix kthread_stop() on ERR_PTR in ftrace-direct-multi-modify
In the Linux kernel, the following vulnerability has been resolved: samples/ftrace: Fix kthreadstop on ERRPTR in ftrace-direct-multi-modify ftracedirectmultiinit assigns kthreadrun's return value to simpletsk without an ISERR check. When kthreadrun fails it returns ERRPTR-ENOMEM, but init still...
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...
