Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: smb: client: fixed a use-after-free in smb2queryinfocompound The following UAF was triggered when running fstests generic/072 with KASAN enabled against Windows Server 2022 and mount options “multichannel, maxChannels=2,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: smb: client: Fixed an oops due to uninitialized variables in smb2unlink. If SMB2openinit or SMB2closeinit fails e.g., due to reconnection, the iovs structure @rqst may remain uninitialized. As a result, calling SMB2openfree,...

EUVD-2026-28634

In the Linux kernel, the following vulnerability has been resolved: smb: client: require a full NFS mode SID before reading mode bits parsedacl treats an ACE SID matching sidunixNFSmode as an NFS mode SID and reads sid.subauth2 to recover the mode bits. That assumes the ACE carries three...

CVE-2026-43362

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...

CVE-2026-43350: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: smb: client: require a full NFS mode SID before reading mode bits parsedacl treats an ACE SID matching sidunixNFSmode as an NFS mode SID and reads sid.subauth2 to recover the mode bits. That assumes the ACE carries three...
