Vulnerability from fkie_nvd - Published: 2024-05-30 16:15 - Updated: 2026-06-17 07:37
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: thermal/debugfs: Free all thermal zone debug memory on zone removal Because thermal_debug_tz_remove() does not free all memory allocated for thermal zone diagnostics, some of that memory becomes unreachable after freeing the thermal zone's struct thermal_debugfs object. Address this by making thermal_debug_tz_remove() free all of the memory in question. Cc :6.8+ <stable@vger.kernel.org> # 6.8+
