Linux Distros Unpatched Vulnerability : CVE-2026-87732

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticatedecryptinto and Chacha20.authenticatedecryptinto functions...

CVE-2026-87733: Improper Certificate Validation

An issue was discovered in the mirage-crypto-ec function before 2.2.0 for OCaml. The ECDSA functions P256,P384,P521.Dsa.pubofoctets accept 0x00, the encoding of the point at infinity, as a public key. With that public key, signatures can be forged without a private key...

CVE-2026-87732: Improper Verification of Cryptographic Signature

An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticatedecryptinto and Chacha20.authenticatedecryptinto functions write the decrypted plaintext into a caller-provided buffer and only then compares the tag. On a forged tag, the functions returns false,...

PT-2026-89091

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: vsie: zero stale crypto bits When shadowing crypto access bits from a format0 apcb crycb 0 or 1, the bits 64..255 are unchanged from whatever is in the vsie page in the crycb and thus in the apcb. This gives a nested...
