kernel: smb: client: validate dacloffset before building DACL pointers

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server can exploit this vulnerability on 32-bit systems by providing a crafted dacloffset value. This can cause a pointer wrap, leading to the dereferencing of invalid Discretionary Access Control List DACL fields...

kernel: smb: client: validate the whole DACL before rewriting it in cifsacl

A flaw was found in the Linux kernel's Server Message Block SMB client, specifically within the cifsacl functionality. A malicious SMB server could provide a malformed Discretionary Access Control List DACL that claims to contain more Access Control Entries ACEs than are actually present. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Use checkaddoverflow to prevent overflow of the u16 DACL size. The functions setposixaclentriesdacl and setntacldacl accumulate the ACE sizes in u16 variables. When a file has many POSIX ACL entries, the accumulated size c...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: smb: client: Validates the entire DACL before rewriting it in the cifsacl format. The functions buildsecdesc and idmodetocifsacl derive a pointer to the DACL from a dacloffset provided by the server. They then use the incoming...
