CVE-2026-90162

In the Linux kernel, the following vulnerability has been resolved: ksmbd: defer publishing granted locks to prevent UAF/double-free race In smb2lock, mid-batch granted locks are published to connection-wide conn-locklist and file-wide fp-locklist lists immediately upon vfslockfile success, while...

CVE-2026-90163

This CVE affects the Linux kernel ksmbd (SMB server) module. When a later initializer during ksmbd module initialization fails, the unwind path releases resources created after the procfs setup but jumps directly to class_unregister() , leaving the proc tree and its per-CPU counters allocated wit...

CVE-2026-90162

CVE-2026-90162 is a Use-After-Free and Double-Free race condition in the Linux kernel's ksmbd (in-kernel SMB server) component, specifically in smb2_lock(). Mid-batch granted locks are published to conn->lock_list and fp->lock_list immediately upon vfs_lock_file() success while also remaini...

CVE-2026-90163

In the Linux kernel, the following vulnerability has been resolved: smb/server: call ksmbdproccleanup on module init failure When a later initializer fails, the unwind chain releases resources created after procfs and then jumps directly to classunregister. Returning an error from moduleinit leav...

CVE-2026-90161

CVE-2026-90161 affects the erofs filesystem driver in the Linux kernel. The root cause is that ztailpacking interlaced pclusters should never be valid, yet crafted images can contain them with non-block-aligned on-disk sizes, leading to an out-of-bounds read from a kmap'd page and copying irrelev...
