SUSE CVE-2026-31717

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate owner of durable handle on reconnect Currently, ksmbd does not verify if the user attempting to reconnect to a durable handle is the same user who originally opened the file. This allows any authenticated user to...

CVE-2026-31718

A flaw was found in ksmbd, the in-kernel SMB3 server for Linux. This vulnerability arises from an asymmetric cleanup process when a durable file handle survives a session disconnect. Specifically, byte-range locks are not properly cleared, leading to a 'use-after-free' error when the durable...

CVE-2026-31717

A flaw was found in ksmbd, a component of the Linux kernel. This vulnerability allows an authenticated user to hijack an orphaned durable handle by predicting or brute-forcing its persistent ID. This could lead to unauthorized access to file sessions and potentially sensitive data or services...

CVE-2026-31711

A flaw was found in the Linux kernel's ksmbd server. An unauthenticated remote attacker can exploit this by holding open connections with large data lengths, leading to a leak of connection resources. This resource exhaustion can prevent new legitimate connections from being established, resultin...

CVE-2026-31707

A flaw was found in the Linux kernel's ksmbd component. A remote attacker could exploit an integer overflow vulnerability when the system processes specially crafted daemon responses. This manipulation of data sizes can bypass internal security checks, leading to memory corruption. Such an issue...

CVE-2026-31706

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB server. An authenticated client can exploit this vulnerability by manipulating the numaces value within the parent directory's security.NTACL extended attribute. This manipulation causes ksmbd to attempt an excessivel...

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-2026-31704

A flaw was found in the ksmbd component of the Linux kernel. This vulnerability arises from an integer overflow when handling Access Control List ACL sizes. When a file is configured with a large number of POSIX ACL entries, the system's calculation of the accumulated size can exceed its designat...
