3) Out-of-bounds read
EUVDB-ID: #VU74392
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-2022-46781
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A local application can trigger an out-of-bounds read error and read contents of memory on the system.
