Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU77254
Risk: Low
CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2020-36694
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the packet processing context, because the per-CPU sequence count is mishandled during concurrent iptables rules replacement. A local user with CAP_NET_ADMIN capability in an unprivileged namespace can execute arbitrary code with elevated privileges.
Install updates from vendor's repository.

2) Use-after-free
EUVDB-ID: #VU62358
Risk: Low
CVSSv4.0: 4.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-1280
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a use-after-free error within the drm_lease_held() function in drivers/gpu/drm/drm_lease.c in the Linux kernel. A local user can run a specially crafted program to trigger a use-after-free error and crash the kernel or gain access to sensitive information.
