CVE-2026-56130 Apache Shiro: Remember-me cookie isn't checked for expiry on the server

"Remember me" cookie age is not verified on the server. This potentially allows an attacker to intercept a valid cookie and reuse it indefinitely, even after the configured expiration time has passed. This issue affects all Apache Shiro versions from 1.2.4 through 2.x, and 3.0.0-alpha-1, only whe...

CVE-2026-56130

The CVE concerns Apache Shiro’s RememberMe functionality: the server does not verify the RememberMe cookie’s age, allowing reuse of a valid cookie beyond its expiration. Affected versions are Apache Shiro 1.2.4 through 2.x, and 3.0.0-alpha-1, only when RememberMe is enabled. The underlying impact...

CVE-2026-53271 ksmbd: fix NULL-deref of opinfo->conn in oplock/lease break notifiers

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix NULL-deref of opinfo-conn in oplock/lease break notifiers smb2oplockbreaknoti and smb2leasebreaknoti read opinfo-conn into a local with neither READONCE nor a NULL check. Both run from oplockbreak after opinfogetlist h...

CVE-2026-53265

The CVE-2026-53265 entry describes a Linux kernel race in the dm-cache policy SMQ path. A check-then-act race occurs in smq_invalidate_mapping where an e->allocated check was left outside the mq->lock after the destructive section was serialized; two concurrent invalidators can observe allo...
