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...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: smb: client: fixed the off-by-8 bounds check in checkwsleas The bounds check uses u8 ea + nlen + 1 + vlen as the end of the EA name and value. However, eadata is located at offset sizeofstruct smb2filefulleainfo = 8 from ea, not ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: smb3: Fixed temporary data corruption during the insert range operation. The insert range does not discard the affected cached data; therefore, there is a risk of temporarily corrupting file data. Some minor optimizations were...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Check outstanding simultaneous SMB operations If a client sends multiple SMB requests to ksmbd, it may exhaust too much memory through the “ksmbdworkcache”. This can lead to an Out-of-Memory error OOM. ksmbd has a credit...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: smb: Client: Fixed an error in parsing OOB read responses for symlinks. When a CREATE command returns STATUSSTOPPEDONSYMLINK, the smb2checkmessage function returns success without performing any length validation. As a result,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: smb: client: Fixed the directory separator in SMB1 UNIX mounts. When calling cifsmountgettcon with SMB1 UNIX mounts, @cifssb-mntcifsflags needs to be read or updated only after calling resetcifsunixcaps. Otherwise, the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: smb: Client: Fixed issue where reference counting of @ses was missed. Use the new cifssmbsesincrefcount helper function to obtain an active reference to @ses and @ses-dfsrootses if set. This will prevent @ses-dfsrootses from...
