CVE-2024-35836

Local kernel crash via stale dpll pin pointer

Published May 17, 2024 · Updated May 11, 2026

Use-after-free in the Linux kernel dpll subsystem 6.7 through 6.7.2 allows local users to crash the kernel via a pin dump. After a bound module is removed while another module retains a pin reference, rebinding leaves the pin's property pointer aimed at freed module memory. Triggering DPLL_CMD_PIN_GET in this rebound state requires local administrative netlink access and interrupts the host by crashing its kernel.
