3) Buffer overflow
EUVDB-ID: #VU62601
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-2022-26490
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the st21nfca_connectivity_event_received() function in drivers/nfc/st21nfca/se.c in Linux kernel. A local user can run a specially crafted program to trigger buffer overflow and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 21 for SLE 15 SP2) to the latest version.
