CVE-2026-44040 UltraVNC vncauth.c uses time-seeded libc rand() to generate VNC authentication challenge bytes

UltraVNC through 1.8.2.2 uses a cryptographically weak pseudo-random number generator to produce VNC authentication challenge bytes. In rfb/vncauth.c:119-129, the vncRandomBytes function seeds libc rand with time0 + getpid + rand and generates a 16-byte challenge. The combined seed space is...

kernel: netfilter: nft_inner: Fix IPv6 inner_thoff desync

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...
