CVE-2026-99277

In the Linux kernel, the following vulnerability has been resolved: ksmbd: hold a connection reference for each session channel ksmbd_session_unregister() removes a session from the global and per- connection tables before dropping the table reference. A concurrent reference holder can keep the session and its channel list alive after those removals. Connection cleanup can no longer find the unpublished session to remove its channels. Since a channel only stores a raw conn pointer, the connection can be freed while another session reference holder is still accessing it, for example during SMB3.1.1 binding or a procfs read. Take a connection reference when registering a channel and release it on insertion failure, channel removal, or final session destruction. Keep the channels and signing keys until the session is destroyed so a response can still be signed after the session has been unregistered.

CVE-2026-123513

Vikunja before 2.7.1 contains a credential exposure vulnerability that allows attackers to steal stored auth tokens by inducing users to switch the frontend API URL. Because checkAndSetApiUrl leaves origin-independent localStorage tokens in place, the bearer token and desktop OAuth refresh token are sent to the attacker's server, enabling account takeover.
