CVE-2026-90148 NFSv4: Fix incorrect argument passed to nfs4_delete_lease() in nfs4_add_lease()

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-2026-90148

CVE-2026-90148 affects the Linux kernel's NFSv4 subsystem. When nfs4_add_lease() races with a delegation return, it passes a potentially NULL priv argument to nfs4_delete_lease(), which eventually leads to a NULL pointer dereference in generic_setlease(). This can cause a kernel crash (panic). Th...

CVE-2026-90139 fuse: check for NULL root inode in fuse_fill_super_submount

In the Linux kernel, the following vulnerability has been resolved: fuse: check for NULL root inode in fusefillsupersubmount fuseiget can return NULL when its inode allocation fails, but fusefillsupersubmount passed the result straight to getfuseinode and decremented fi-nlookup without checking i...

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-2026-90130

CVE-2026-90130 is a Linux kernel vulnerability in the vdpa_sim module. When kthread_run_worker() fails during device creation, vdpasim_create() leaves vdpasim->worker as an ERR_PTR . The subsequent error path releases the partially initialized simulator, and vdpasim_free() unconditionally pass...

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...

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pnfs: key the data server cache on the NFS version nfs4pnfsdsadd keys the per-net data server cache on the multipath address set alone, and struct nfs4pnfsds records no version. That suffices for the files layout driver,...

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 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.

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-2026-90080
