Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
EUVDB-ID: #VU66588
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-36557
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition between the VT_DISALLOCATE IOCTL and closing/opening of ttys. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
MitigationUpdate the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-1462
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the the Linux kernel’s TeleTYpe subsystem caused by a race condition when using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory file. A local user can trigger an out-of-bounds read error and crash the system or read random kernel memory.

CVE-ID: CVE-2022-36946
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input within the nfqnl_mangle() function in net/netfilter/nfnetlink_queue.c in the Linux kernel when processing IPv6 packets. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.
