CVE-2026-64289

A flaw was found in the Linux kernel. In the iommufd component, the iommufdhwptinvalidate function allows a local user to provide excessively large values for entrynum and entrylen during cache invalidation. This can lead to a Denial of Service DoS by causing the system to become unresponsive...

The vulnerability of the cfids_invalidation_worker() function in the fs/smb/client/cached_dir.c module allows a hacker to trigger a service failure in Linux-based operating systems with SMB client support.

The vulnerability of the cfidsinvalidationworker function in the fs/smb/client/cacheddir.c module of the SMB client kernel in Linux operating systems is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to cause a service failure...

Insufficient Session Expiration

code.gitea.io/gitea is vulnerable to Insufficient Session Expiration. The vulnerability is due to improper invalidation of compromised Remember-Me session tokens, which allows an attacker to maintain unauthorized, persistent access to a user's account by reusing a stolen token even after the...
