Vulnerability identifier: #VU93349

CSH Severity: Low

CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2024-35836

CWE-ID: CWE-416

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the dpll_msg_add_pin_freq(), dpll_pin_is_freq_supported(), dpll_cmd_pin_get_one(), dpll_pin_on_pin_state_set(), dpll_pin_state_set(), dpll_pin_prio_set(), dpll_pin_direction_set(), dpll_pin_phase_adj_set() and dpll_pin_find() functions in drivers/dpll/dpll_netlink.c, within the dpll_device_unregister(), dpll_pin_alloc(), dpll_pin_put() and dpll_pin_on_pin_register() functions in drivers/dpll/dpll_core.c. A local user can escalate privileges on the system.
