12 May 2020 — A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NU... • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html • CWE-476: NULL Pointer Dereference •

12 May 2020 — A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial... • https://bugzilla.redhat.com/show_bug.cgi?id=1822077 • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-190: Integer Overflow or Wraparound •

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 •
