Astra Linux – Vulnerability in Linux 5.15
A flaw was discovered in the ksmbd component of the Linux kernel. A memory leak may occur if a client sends a session setup request with an unknown NTLMSSP message type, potentially leading to resource exhaustion...
Astra Linux – Vulnerability in Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Corrected the incorrect validation of the next buffer length in smb2setea. There are multiple smb2eainfo buffers in the FILEFULLEAINFORMATION request from the client. ksmbd uses the NextEntryOffset of the current...
CVE-2026-64390
A flaw was found in the Linux kernel's ksmbd component, which provides Server Message Block SMB protocol support. This vulnerability involves incorrect management of byte-range locks when multiple connections are used with SMB3 multichannel. An attacker could exploit this by sending specially...
CVE-2026-64393
A flaw was found in the Linux kernel's ksmbd component. This vulnerability allows a local attacker to escalate privileges by manipulating Server Message Block SMB2 SETINFO operations. The system incorrectly uses the ksmbd worker's credentials instead of the original user's credentials when...
CVE-2026-64391
In the Linux kernel, the following vulnerability has been resolved: ksmbd: use opener credentials for ADS I/O Alternate data streams are stored as xattrs. Unlike regular file I/O, their read and write paths therefore call VFS xattr helpers which recheck inode permissions and LSM policy using the...
CVE-2026-53390
A flaw was found in the Linux kernel's ksmbd component. An authenticated client can exploit an out-of-bounds read vulnerability in the smbcheckpermdacl function by providing a specially crafted Access Control Entry ACE. This crafted ACE, when processed during an access check on a share that uses...
CVE-2026-53383
A flaw was found in the Linux kernel's ksmbd component. A remote attacker can trigger a NULL pointer dereference by sending a specially crafted compound SMB2 request. This occurs because the session validation logic for non-first operations in a compound request does not properly check the sessio...
CVE-2026-53010
A flaw was found in the Linux kernel's ksmbd component. During a durable reconnect process in the smb2open function, a reference to a durable file descriptor is prematurely dropped. This can lead to a use-after-free vulnerability, potentially resulting in system instability or a denial of service...
CVE-2026-52944
A flaw was found in the Linux kernel's ksmbd component. This vulnerability allows a client to bypass intended permission restrictions by using the FSCTLSETSPARSE operation. Specifically, a client on a read-only share can modify a file's sparse attribute, and clients on writable shares can modify...
CVE-2026-52911
A flaw was found in the ksmbd component of the Linux kernel. This vulnerability allows an attacker to gain unauthorized access to session information or resources by exploiting an improper scope in the session binding mechanism. This could potentially compromise the integrity or confidentiality o...
CVE-2026-45924
A flaw was found in ksmbd, a component of the Linux kernel. This vulnerability occurs because ksmbdvfskernpathendremoving is not called on certain error paths, leading to unbalanced inode locks and references. This can result in potential deadlocks and unbalanced locks, which may cause system...
CVE-2026-31705
A flaw was found in the ksmbd component of the Linux kernel. This out-of-bounds write vulnerability occurs when processing Server Message Block SMB extended attribute EA information. Specifically, the smb2getea function performs an unconditional memory write for alignment padding without checking...
CVE-2026-31611
A flaw was found in the ksmbd component of the Linux kernel. A remote attacker could exploit this vulnerability by sending a specially crafted Access Control Entry ACE that causes an out-of-bounds read when parsing security identifiers. This out-of-bounds read can lead to the application of...
CVE-2026-23428
A flaw was found in ksmbd, a component of the Linux kernel. This use-after-free vulnerability occurs during the processing of Server Message Block version 2 SMB2 compound requests. An attacker could exploit this by sending a specially crafted sequence of SMB2 commands, causing the system to attem...
ROS-20260324-73-0002
A vulnerability in the generateencryptionkey function of the ksmbd component of the Linux kernel is related to the dereferencing of a NULL pointer. Exploitation of the vulnerability could allow an attacker to cause a denial of service...
ROS-20260121-73-0033
A vulnerability in the ksmbd component of the Linux kernel is related to the use of memory after it has been freed. Exploitation of the vulnerability may allow an attacker to gain access to sensitive data, compromise its integrity, and cause denial of service...
ROS-20260119-7349
A vulnerability in the ksmbd component of the Linux operating system kernel is related to integer overflow. Exploitation of the vulnerability could allow an attacker to cause a denial of service...
The vulnerability of the opinfo_get_list() function in the ksmbd component of the Linux operating system allows a hacker to trigger a service failure.
The vulnerability of the opinfogetlist function in the ksmbd component of the Linux operating system is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...
PT-2025-44380
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel’s ksmbd component contains a flaw related to recursive locking within RPC handle list access. Specifically, the ksmbd session rpc method function attempts to lock sess-r...
