Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: cifs: parsedfsreferrals: prevents out-of-bounds access on malformed inputs A malicious SMB server can send invalid responses to FSCTLDFSGETREFERRALS. - The response is smaller than sizeofstruct getdfsreferralrsp. - The number of...

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...
