Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed an improper scalar handling in the maybeforkscalars function for BPFOR. The maybeforkscalars function is called for both BPFAND and BPFOR when the source operand is a constant. When dst has a signed range of -1, 0, it...

CVE-2026-41564

CVE-2026-41564 concerns CryptX for Perl before 0.088, where per-object PRNG state seeded in Crypt::PK::* constructors is not reseeded after fork. A Crypt::PK::* object created before a fork can be inherited by multiple child processes with byte-identical PRNG state, enabling identical outputs in ...

CVE-2026-41564 CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking

CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking. The Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519 modules seed a per-object PRNG state in their constructors and reuse it without fork detection. A...

An incorrect authorization vulnerability was identified in GitHub Enterprise Server that allowed an attacker to merge their own pull request into a repository without having push access by exploiting an authorization bypass in the enableautomerge mutation for pull requests. This issue only affect...

CVE-2025-7105

A vulnerability in danny-avila/librechat allows attackers to exploit the unrestricted Fork Function in /api/convos/fork to fork numerous contents rapidly. If the forked content includes a Mermaid graph with a large number of nodes, it can lead to a JavaScript heap out of memory error upon service...
