CVE-2026-64386

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the queryinfo replay mechanism attempts to free a response buffer that has already been released. This can happen if an error occurs during the initialization of an SMB2...

The vulnerability of the smb_lazy_parent_lease_break_close() function in the fs/smb/server/oplock.c module of the Smb subsystem of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the smblazyparentleasebreakclose function in the fs/smb/server/oplock.c module of the Smb subsystem of the Linux operating system is related to the reutilization of previously freed memory due to concurrent access to resources. Exploiting this vulnerability could allow a remo...

CVE-2026-64391

A flaw was found in ksmbd, the in-kernel Server Message Block SMB daemon. This vulnerability allows a remote attacker to bypass security restrictions by incorrectly handling credentials for Alternate Data Streams ADS input/output I/O operations. Instead of using the credentials established when t...

CVE-2026-64379

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing server-provided file mode information, the system incorrectly applies these modes without proper security masking. This can result in unintended file permissions, potentially allowing unauthorized access to...

CVE-2026-64402

A flaw was found in the Linux kernel's coresight ultrasoc-smb component. This vulnerability involves an out-of-bounds write in the smbsyncperfbuffer function. An attacker could potentially exploit this by causing the system to write data beyond the intended memory buffer, which may lead to system...

CVE-2026-64387

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the client attempts to free the same memory buffer twice during a directory query operation. An attacker could potentially exploit this flaw to cause memory corruption,...
