CVE-2026-43362 smb: client: fix in-place encryption corruption in SMB2_write()

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix in-place encryption corruption in SMB2write SMB2write places write payload in iov1..n as part of rqiov. smb3inittransformrq pointer-shares rqiov, so cryptmessage encrypts iov1 in-place, replacing the original...

CVE-2026-43362

CVE-2026-43362 affects the Linux kernel SMB client by an in-place encryption flaw in SMB2_write(), where the write payload could be replaced with ciphertext during retries on unstable connections. The root cause is that smb3_init_transform_rq() shares rq_iov, causing crypt_message() to in-place-e...

CVE-2026-43350

In the Linux kernel, a vulnerability in the SMB client path can allow a malicious server to exploit an ACE with sid_unix_NFS_mode by providing an ACE with only two subauthorities. parse_dacl() would treat this as an NFS mode SID and read sub_auth[2], potentially reading four bytes past the end of...
