CVE-2020-10690 (GCVE-0-2020-10690)
Vulnerability from cvelistv5 – Published: 2020-05-08 13:48 – Updated: 2024-08-04 11:06
VLAI
EPSS
VEX
Summary
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 pointed to by the inode.

Summary
A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing.

CVE-2020-11565 (GCVE-0-2020-11565)
Vulnerability from cvelistv5 – Published: 2020-04-06 00:08 – Updated: 2024-08-04 11:35 Disputed
VLAI
EPSS
VEX
Summary
An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue “is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.”

CVE-2020-12826 (GCVE-0-2020-12826)
Vulnerability from cvelistv5 – Published: 2020-05-12 18:58 – Updated: 2024-08-04 12:04
VLAI
EPSS
VEX
Summary
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 operational threat.
Severity
No CVSS data available.
