Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: Fixed a memory leak in seg6hmacinitalgo. seg6hmacinitalgo returns without cleaning up previously allocated memory. If this happens, all that memory will be leaked, potentially causing issues with crypto-related function...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when setting HMAC data. The SRv6 layer allows defining HMAC data that can later be used to sign IPv6 Segment Routing Headers. This configuration is realized through netlink using four attributes:...

CVE-2026-75870

Punk versions before 0.18 for Perl allow session cookie forgery via an empty default HMAC key when a session is declared without a secret. The session keyword freezes its options onto the application as given: it does not require a secret, warn, or refuse to start when one is absent. The cookie...

CVE-2026-75870

CVE-2026-75870 affects the Punk Perl web framework (by LNATION) in versions before 0.18 . When the session keyword is declared without a secret option (or with an undefined/empty one), both cookie read and write-back default the HMAC key to an empty string , resulting in a zero-length HMAC-SHA256...

CVE-2025-30156

A flaw was found in the CephX authentication protocol used by Ceph, a distributed storage system. CephX uses AES-128-CBC encryption with a hardcoded initialization vector and no message authentication HMAC, making it vulnerable to the same class of unauthenticated-encryption attacks that...

CVE-2026-68554

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.15.0, an on-path attacker can append attributes after MESSAGE-INTEGRITY to an authenticated STUN request on plain UDP or TCP, adjust the STUN header length, and recompute the unkeyed FINGERPRINT while the original HMA...

CVE-2026-68554 Coturn: STUN attributes after MESSAGE-INTEGRITY are processed, letting on-path attackers modify authenticated TURN requests

Coturn is a free open source implementation of TURN and STUN Server.

CVE-2026-68554

Coturn (open-source TURN/STUN server) prior to 4.15.0 is vulnerable to an on-path STUN message truncation attack. The root cause is that the server-side parser in src/server/ns_turn_server.c continues processing attributes after the MESSAGE-INTEGRITY field. Since the HMAC covers only the message ...

CVE-2026-75589

A flaw was found in Net::OAuth. This vulnerability arises from a non-constant-time comparison used when verifying HMAC-SHA1, HMAC-SHA256, and PLAINTEXT signatures. A remote attacker could exploit this by timing the responses to submitted messages, allowing them to recover valid signatures or, in...

CVE-2026-75589

Net::OAuth versions before 0.33 for Perl check HMAC-SHA1, HMAC-SHA256 and PLAINTEXT signatures with a non-constant-time comparison in verify. Each of the three compares the signature carried in the message against the locally computed one with the eq operator, which returns as soon as the two...
