CVE-2026-90164 smb/server: abort initialization when proc setup fails

In the Linux kernel, the following vulnerability has been resolved: smb/server: abort initialization when proc setup fails ksmbdserverinit calls ksmbdprocinit before creating the remaining proc entries and server subsystems. ksmbdprocinit tears down partial state on a procfs or percpucounter...

CVE-2026-90164

CVE-2026-90164 affects the ksmbd (SMB server) subsystem in the Linux kernel . The root cause is that ksmbd_proc_init() returns void after a procfs or percpu_counter allocation failure, causing ksmbd_server_init() to continue with NULL per-CPU counters. On SMP systems , this leads to a NULL pointe...

CVE-2026-90156

CVE-2026-90156 affects the ksmbd (SMB server) module in the Linux kernel . The vulnerability is a NULL pointer dereference in the lock rollback path: when vfs_lock_file() defers a lock, smb2_lock() places its ksmbd_lock on the rollback list before allocating and registering the asynchronous work....

CVE-2026-90156 ksmbd: safely discard unregistered deferred locks

In the Linux kernel, the following vulnerability has been resolved: ksmbd: safely discard unregistered deferred locks When vfslockfile defers a lock, smb2lock puts its ksmbdlock on rollbacklist before allocating and registering the asynchronous work. If either operation fails, rollback assumes th...

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...

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-2026-90115 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...
