CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a buffer overflow in the jfs file system's xattr functionality. When an xattr size is not as expected, it is printed out to the kernel log in hex format for debugging purposes. However, if the xattr size is larger than expected, printing it can cause an access off the end of the buffer. This is fixed by properly restricting the size of the debug hex dump in the kernel log. The vulnerability may allow an attacker to impact the confidentiality, integrity, and availability of protected information.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
