kernel: iommu/vt-d: Clear Present bit before tearing down PASID entry

A flaw was found in the Linux kernel's Intel VT-d Virtualization Technology for Directed I/O Scalable Mode. When a Process Address Space ID PASID table entry is being removed, the system may attempt to clear the entry before properly signaling to the hardware that the entry is no longer active...

CVE-2026-77987

A server-side request forgery SSRF vulnerability was identified in the notebook viewer of GitHub Enterprise Server. The notebook viewer validated the scheme and host of a user-supplied URL but did not validate the port, allowing requests to be directed to internal services listening on other port...

CVE-2026-77987 GitHub Enterprise Server notebook viewer vulnerable to Server-side request forgery

A server-side request forgery SSRF vulnerability was identified in the notebook viewer of GitHub Enterprise Server. The notebook viewer validated the scheme and host of a user-supplied URL but did not validate the port, allowing requests to be directed to internal services listening on other port...

CVE-2026-77987

A server-side request forgery (SSRF) vulnerability exists in the notebook viewer of GitHub Enterprise Server (versions 3.17 through 3.22). The root cause is the failure to validate the port of user-supplied URLs, despite validating the scheme and host. This allows requests to internal services on...

GHSA-8FCF-V89G-XPG6 Traefik: BasicAuth singleflight coalescing reintroduces an unauthenticated username-enumeration timing oracle

Summary Traefik's BasicAuth middleware coalesces concurrent credential checks through a singleflight.Group to avoid hashing the same password many times at once. Since v3.6.11 the deduplication key was built from the submitted password plus the stored secret, so it depended on server state: a...

GHSA-C759-CX9P-MRWQ lightrag-hku: Plaintext Passwords Compared Without Constant-Time Function

Summary When plaintext passwords are stored in AUTHACCOUNTS, the comparison uses Python's == operator which is not constant-time. An attacker with low-latency access can exploit timing differences to recover the password character by character. Details python lightrag/api/passwords.py:13-26 def...

GHSA-456H-WW26-F758 Tinyauth: User enumeration attack by timing oracle

Summary It's possible to enumerate users through a timing oracle. In other words: I can easily check if a username exists or not by observing the timing differences between logins. PoC Setup a tinyauth server with a local user. It can be over the network. Try to log in with the local user, using ...

GHSA-34FC-GH42-PJ53 OpenBao's Recovery Mode Vulnerable To Token Leakage via Timing Attack

Impact When running in the highly privileged recovery mode, OpenBao was vulnerable to a timing attack against the single recovery token. This allowed an attacker to extract the recovery token and use it to perform operations against the OpenBao instance, including reading or modification of data...

Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack via the recovery token comparison in handleLogicalRecovery in http/logical.go. An attacker can extract the single recovery token and use it to perform privileged recovery-mode API operations by repeatedly sending candidate...
