Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: NFSD: Prevention of potential integer overflows If the tag length is greater than or equal to U32MAX – 3, the addition of “length + 4” can lead to an integer overflow. This issue can be addressed by breaking down the decoding...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: Fixed a potential out-of-bound read issue in ext4fcreplayscan. For the scan loop, it is necessary to ensure that at least EXT4FCTAGBASELEN space is available. If the remaining space is less than EXT4FCTAGBASELEN, it may lea...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in the Linux kernel before version 6.3.4. ksmbd has a buffer overflow vulnerability in the smb2findcontextvals function, when the namelen of createcontext is larger than the length of the tag...

USN-8720-1 gnupg2 vulnerability

It was discovered that GnuPG incorrectly validated authentication tag lengths when parsing CMS messages encrypted with AES-GCM. An attacker could possibly use this issue to bypass message integrity checks...

openssl: CMS AuthEnvelopedData Processing May Accept Forged Messages

A flaw was found in OpenSSL's Cryptographic Message Services CMS AuthEnvelopedData processing. An on-path attacker can exploit insufficient input validation on cipher and tag length fields by sending specially crafted CMS messages. This can lead to the forging of messages or bypassing integrity...

CVE-2026-5855 Contiki-NG LwM2M TLV Parser Out-of-Bounds Read via Unchecked Buffer Length in lwm2m_tlv_read

Contiki-NG's LwM2M TLV parser lwm2mtlvread in os/services/lwm2m/lwm2m-tlv.c ignores its caller-supplied buffer length argument and reads up to six bytes from the input buffer with no bounds check. The caller in lwm2m-engine.c iterates while there is at least one byte remaining, so a crafted CoAP...
