Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU68423
Risk: Low
CVSSv4.0: 6.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-2602
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error caused by an io_uring request, which is being processed on a registered file. The Unix GC runs and frees the io_uring file descriptor and all the registered file descriptors in a specific order that may allow a local user to win a race and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 4 for SLE 15 SP4) to the latest version.

2) Use-after-free
EUVDB-ID: #VU69759
Risk: Low
CVSSv4.0: 5.9 [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:U/U:Clear]
CVE-ID: CVE-2022-3424
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 within the gru_set_context_option(), gru_fault() and gru_handle_user_call_os() functions in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 4 for SLE 15 SP4) to the latest version.
