CVE-2026-77584

Tor before 0.4.9.10 did not reject a CONFLUXLINK cell that arrives on a circuit which already has attached streams. A malicious client could send a RELAYCOMMANDBEGIN before the CONFLUXLINK on the same circuit, attaching an exit stream that would later end up orphan leaving a dangling circuit...

CVE-2026-74359

A flaw was found in the Linux kernel's configfs component. This vulnerability occurs because a memory pointer is not properly cleared after a failure, leading to a 'use-after-free' condition. A local attacker could exploit this by interacting with the affected directory, which could cause memory...

CVE-2026-74345

A flaw was found in the Linux kernel's Soft iWARP siw component, which handles high-performance data transfer.

Zoo Design Studio: Memory-corruption in memory handling of lib-kcl

A race condition in kcl-lib can result in a use-after-free when accessing environments concurrently. During Vec reallocation, the previous buffer containing Box pointers is freed and replaced. A concurrent getenv operation that has already loaded a pointer to the old buffer may subsequently index...
