kernel: smb: client: protect tc_count increment in smb2_find_smb_sess_tcon_unlocked()

A flaw was found in the Linux kernel's Server Message Block SMB client. A missing lock around the tccount increment in the smb2findsmbsesstconunlocked function creates a race condition. This vulnerability, caused by an incomplete refactoring of locking mechanisms, could lead to unexpected behavio...

kernel: smb: client: fix change notify replay double-free

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies. If a response attempt returns a replayable error and frees its buffer, and then SMB2notifyinit fails, the same buffer can be freed agai...

kernel: smb: client: validate DFS referral PathConsumed

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System DFS referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds...

kernel: smb/client: fix out-of-bounds read in smb2_compound_op()

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker, acting as a malicious SMB server, could send a specially crafted, truncated response with an oversized buffer length. This could lead to an out-of-bounds read in the smb2compoundop function, allowing the...
