Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Out-of-bounds read
EUVDB-ID: #VU78725
Risk: Low
CVSSv4.0: 4.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-48502
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 ntfs_set_ea() function in fs/ntfs3/xattr.c in Linux kernel ntfs3 subsystem. A local user can trigger an out-of-bounds read error and read contents of memory on the system or crash the OS kernel.
MitigationInstall updates from vendor's repository.
