CVE-2026-48526

PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer public key as the...

Triton VM has a Soundness Vulnerability due to Improper Sampling of Randomness

In affected versions of Triton VM, the verifier failed to correctly sample randomness in the FRI sub-protocol. Malicious provers can exploit this to craft proofs for arbitrary statements that this verifier accepts as valid, undermining soundness. Protocols that rely on proofs and the supplied...

CVE-2024-58098 bpf: track changes_pkt_data property for global functions

In the Linux kernel, the following vulnerability has been resolved: bpf: track changespktdata property for global functions When processing calls to certain helpers, verifier invalidates all packet pointers in a current state. For example, consider the following program: attributenoinline long...

GHSA-WWX5-GPGR-VXR7 ismp-grandpa crate accepted incorrect signatures

A critical vulnerability was discovered in the ismp-grandpa crate, that allowed a malicious prover easily convince the verifier of the finality of arbitrary headers. Description The vulnerability manifests as a verifer that only accepts incorrect signatures of Grandpa precommits and was introduce...

LSN-0082-1 Kernel Live Patch Security Notice

Jann Horn discovered that the tty subsystem of the Linux kernel did not use consistent locking in some situations, leading to a read-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly expose sensitive information kernel...

CVE-2021-3444

The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure kernel...
