Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Double Free
EUVDB-ID: #VU66397
Risk: Low
CVSSv3.1: 7.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:H/RL:O/RC:C]
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.
Update the affected package the Linux Kernel (Live Patch 33 for SLE 15 SP1) to the latest version.

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?
Yes. This vulnerability is being exploited in the wild.
2) Use-after-free
EUVDB-ID: #VU69297
Risk: Low
CVSSv3.1: 5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
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.
Update the affected package the Linux Kernel (Live Patch 33 for SLE 15 SP1) to the latest version.
