Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU85442
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-6606
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a boundary condition within the smbCalcSize() function in fs/smb/client/netmisc.c file. A local user can trigger an out-of-bounds read error and gain access to sensitive information or crash the kernel.
MitigationInstall updates from vendor's repository.
