CVE-2026-41489

Pi-hole (6.0 through before Core 6.4.2 and FTL 6.6.1) is vulnerable because two systemd-executed root scripts (pihole-FTL-prestart.sh and pihole-FTL-poststop.sh) read the files.pid path from a config without validation and perform privileged file operations using that path. An attacker with pihol...

CVE-2026-41489 Pi-hole: Local privilege escalation via config-controlled path in root-executed service hooks

Pi-hole is a DNS sinkhole that protects devices from unwanted content without installing any client-side software. From 6.0 to before Core 6.4.2 and FTL 6.6.1, two shell scripts executed as root by systemd pihole-FTL-prestart.sh and pihole-FTL-poststop.sh read the files.pid path from this config...

CVE-2026-28915

A parsing issue in the handling of directory paths was addressed with improved path validation. This issue is fixed in macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5. An app may be able to gain root privileges...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

CVE-2026-43500

A flaw was found in the Linux kernel's RxRPC networking subsystem. When a socket buffer carrying a page-cache reference reaches the RxRPC authentication verification path, the kernel performs an in-place decryption directly on the referenced page without first isolating the buffer. A low-privileg...
