CVE-2024-36956 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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+. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
