| CVE-2020-10773 | Med | 0.00 | 4.4 | 0.00 | Sep 10, 2020 | A stack information leak flaw was found in s390/s390x in the Linux kernel’s memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the kernel data. | ||
| CVE-2020-25220 | Hig | 0.00 | 7.8 | 0.00 | Sep 10, 2020 | The Linux kernel 4.9.x before 4.9.233, 4.14.x before 4.14.194, and 4.19.x before 4.19.140 has a use-after-free because skcd->no_refcnt was not considered during a backport of a CVE-2020-14356 patch. This is related to the cgroups feature. | ||
