{"id":"DEBIAN-CVE-2024-36932","details":"In the Linux kernel, the following vulnerability has been resolved:  thermal/debugfs: Prevent use-after-free from occurring after cdev removal  Since thermal_debug_cdev_remove() does not run under cdev-\u003elock, it can run in parallel with thermal_debug_cdev_state_update() and it may free the struct thermal_debugfs object used by the latter after it has been checked against NULL.  If that happens, thermal_debug_cdev_state_update() will access memory that has been freed already causing the kernel to crash.  Address this by using cdev-\u003elock in thermal_debug_cdev_remove() around the cdev-\u003edebugfs value check (in case the same cdev is removed at the same time in two different threads) and its reset to NULL.
