Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU69297
Risk: Low
CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-42703
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the mm/rmap.c in the Linux kernel, related to leaf anon_vma double reuse. A local user can trigger a use-after-free error and crash the kernel.
Install updates from vendor's repository.

2) Stack-based buffer overflow
EUVDB-ID: #VU70442
Risk: Low
CVSSv4.0: 7.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-4378
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.
