Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Security restrictions bypass
EUVDB-ID: #VU66549
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-26373
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to non-transparent sharing of return predictor targets between contexts in Intel CPU processors. A local user can bypass the expected architecture isolation between contexts and gain access to sensitive information on the system.
MitigationInstall updates from vendor's repository.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Double Free
EUVDB-ID: #VU66397
Risk: Low
CVSSv4.0: 8.5 [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:A/U:Clear]
CVE-ID: CVE-2022-2588
CWE-ID:
CWE-415 - Double Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The
vulnerability exists due to a double free error within the network packet scheduler implementation
in the route4_change() function in Linux kernel when removing all references to a route filter
before freeing it. A local user can run a specially crafted program to
crash the kernel or execute arbitrary code.
