SUSE CVE-2026-72382

In the Linux kernel, the following vulnerability has been resolved: ksmbd: reject undersized DACLs before parsing ACEs parsedacl limits the attacker-controlled ACE count by comparing it with the number of minimal ACEs that fit in the DACL size. The DACL size field is 16 bits, but the expression...

The vulnerability of the parse_dacl() function in the fs/smb/server/smbacl.c file of the Smb file system in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the parsedacl function in the fs/smb/server/smbacl.c file of the Smb file system in the Linux operating system is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability could allow a remote attacker to compromise the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Rejects undersized DACLs before parsing ACEs The parsedacl function limits the number of attacker-controlled ACE entries by comparing it with the minimum number of ACE entries that fit within the DACL size. The DACL size...

CVE-2026-64379

In the Linux kernel, the following vulnerability has been resolved: smb: client: mask server-provided mode to 07777 in modefromsid When modefromsid is active, parsedacl applies the server-provided subauth2 value from the NFS mode SID to cfmode without masking to 07777. Apply the correct masking,...

CVE-2026-64379: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: smb: client: mask server-provided mode to 07777 in modefromsid When modefromsid is active, parsedacl applies the server-provided subauth2 value from the NFS mode SID to cfmode without masking to 07777. Apply the correct masking,...

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...

AZL-83753 CVE-2026-31611 affecting package kernel for versions less than 6.6.137.1-1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: require 3 sub-authorities before reading subauth2 parsedacl compares each ACE SID against sidunixNFSmode and on match reads sid.subauth2 as the file mode. If sidunixNFSmode is the prefix S-1-5-88-3 with numsubauth = 2 then...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the number of sub-authorizations is not verified before reading subauth2 in parsedacl,...
