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-2026-41489

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...

EUVD-2026-28572

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Set DMA segment size to avoid debug warnings When using V3D rendering with CONFIGDMAAPIDEBUG enabled, the kernel occasionally reports a segment size mismatch. This is because 'maxsegsize' is not set. The kernel defaults ...

PT-2026-38944

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the drm/v3d component where the max seg size is not set when using V3D rendering with CONFIG DMA API DEBUG enabled. This causes the kernel to default to a 64K segment...
