Off By !: Exploiting a Use-after-Free in the Linux Kernel
Exodus Intelligence disclosed a use-after-free vulnerability (CVE-2026-23111) in the Linux kernel's nftables subsystem affecting the pipapo set implementation. The flaw exists in the nft_map_catchall_activate() function which incorrectly skips deactivated catchall elements during abort processing, leaving reference counters in an inconsistent state. This enables local privilege escalation from unprivileged user to root on Debian Bookworm, Debian Trixie, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS; the vulnerability was patched upstream on 5 February 2026.

Old WinRAR Flaw Fuels Attacks on Ukraine: How Unmanaged Software Keeps the Door Open
WinRAR path-traversal vulnerability CVE-2025-8088 (CVSS 8.4), patched in July 2025, continues to be actively exploited by multiple Russia-aligned threat actors including SHADOW-EARTH-066 (UAC-0226) and Earth Dahu (Gamaredon) against Ukrainian targets through April 2026. The flaw exploits NTFS Alternate Data Streams to silently write files outside extraction directories, enabling initial access via email-delivered RAR archives with decoy documents. SHADOW-EARTH-066 has evolved from basic Excel macro droppers with plaintext Telegram exfiltration to sophisticated WinRAR exploit chains delivering an updated GIFTEDCROOK information stealer with in-memory DLL loading, dual-layer RC4 encryption, Chrome App-Bound Encryption bypass, and dedicated C&C infrastructure.
