EUVD-2026-103694

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix create context out-of-bounds reads smb2parsecontexts validates the complete create-context area but does not limit each record to its Next field before dispatching it. A malformed chain can therefore expose bytes...

CVE-2026-90165

A flaw was found in the Linux kernel's ksmbd server. This vulnerability occurs when the ksmbdstopdurablescavenger function attempts to stop a kernel thread that was not properly initialized, leading to an invalid pointer dereference. An attacker could potentially exploit this to cause a system...

CVE-2026-90174

A flaw was found in ksmbd in the Linux kernel. A remote attacker can send a specially crafted login response with an oversized hash size during the authentication process. This can lead to a slab-out-of-bounds read in the ksmbdallocuser function, potentially resulting in information disclosure or...
