Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU66807
Risk: Low
CVSSv4.0: 4.3 [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:U/U:Clear]
CVE-ID: CVE-2022-2873
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to crash the kernel.
The vulnerability exists due to a boundary condition within the Intel iSMT SMBus host controller driver. A local user can send specially crafted data to the I2C_SMBUS IOCTL, trigger an out-of-bounds read error and crash 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) 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.
