Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU73280
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-1380
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the Broadcom Full MAC Wi-Fi driver (brcmfmac.ko). A local user can trigger an out-of-bounds read error and read contents of kernel memory on the system.
MitigationUpdate the affected package linux-intel-iotg-5.15 to the latest version.

EUVDB-ID: #VU76655
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-2023-2612
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition within the shiftfs filesystem when handling inode locking in some
situations. A local user can exploit the race and cause a denial of service (kernel deadlock).
Update the affected package linux-intel-iotg-5.15 to the latest version.
