CVE-2026-74576

A flaw was found in the Linux kernel's memory management. This vulnerability allows for unbounded recursion in the slab free path, a process where the kernel manages and releases small blocks of memory. When certain kernel memory allocation caches kmalloc caches form a cycle during internal data...

CVE-2026-74576

Summary of CVE-2026-74576 (Linux kernel) : The vulnerability stems from the slab allocator allowing unbounded recursion in the free path due to cycles formed when obj_exts arrays are allocated across KMALLOC_NORMAL caches. Specifically, slabs can form a cycle by allocating each other’s obj_exts a...

CVE-2026-45246

CVE-2026-45246 describes an insecure file permission vulnerability in the refresh-free configuration rewrite path for versions prior to 0.15.1. When the path rewrites the configuration file, the replacement is created with default process umask permissions instead of preserving the original file ...

CVE-2026-45246 Summarize < 0.15.1 Insecure File Permissions Information Disclosure

Summarize prior to 0.15.1 contains an insecure file permission vulnerability in the refresh-free configuration rewrite path that allows local users to read sensitive credentials by exploiting default filesystem permissions. When the refresh-free path rewrites the configuration file, it creates th...
