CVE-2020-10690 – kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open
https://notcve.org/view.php?id=CVE-2020-10690
08 May 2020 — There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointe... • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html • CWE-416: Use After Free •

It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of memory they li... • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html • CWE-401: Missing Release of Memory after Effective Lifetime •
