SUSE CVE-2026-53081

In the Linux kernel, the following vulnerability has been resolved: bpf: Enforce regsafe base id consistency for BPFADDCONST scalars When regsafe compares two scalar registers that both carry BPFADDCONST, checkscalarids maps their full compound id aka base | BPFADDCONST flag as one idmap entry...

SUSE CVE-2026-53092

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix linked reg delta tracking when srcreg == dstreg Consider the case of rX += rX where srcreg and dstreg are pointers to the same bpfregstate in adjustregminmaxvals. The latter first modifies the dstreg in-place, and later ...

GHSA-4V2W-2WQP-MC85 OpenAM OAuth Authorization Bypass via PKCE Challenge

Summary Description An Improper Authorization CWE-285 issue in OpenAM's OAuth2 authorization-code grant allows a PKCE-protected authorization code to be redeemed without the required codeverifier. This affects OpenAM Community Edition through version 16.0.6 and was patched in version 16.1.1. The...

CVE-2026-53092

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability occurs due to incorrect delta tracking when source and destination registers are the same during register value adjustments. This can lead to a mismatch between the BPF verifier's analysis and the actu...

CVE-2026-47775

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.35.11, 1.36.7, 1.37.3, and 1.38.1, the OAuth2 HTTP filter's encrypt/decrypt functions use AES-256-CBC without an authentication tag no HMAC, no AEAD. The /callback endpoint returns HTTP 302 on...

CVE-2026-53081

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs due to inconsistent base ID mapping when the regsafe function compares scalar registers with BPFADDCONST values. This inconsistency allows the BPF verifier to incorrectly succeed in state pruning...

CVE-2026-53090

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. When ldabs,ind instructions are used in BPF subprograms, the verifier fails to correctly simulate the abnormal exit path if packet data loading fails. This oversight could lead to unexpected behavior or bypass of security...
