| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel version 2.6
ext4dev-kmp-trace (affected versions not specified)
Description
The issue concerns a denial of service in the Linux kernel, specifically through the hfs find init function when mounting an HFS file system with a malformed MDB extent record, leading to a NULL pointer dereference and Oops. Additionally, there are multiple vulnerabilities in the ext4dev-kmp-trace package of SUSE Linux Enterprise that can be exploited remotely, potentially disrupting the availability of protected information.
Recommendations
For Linux kernel version 2.6, consider disabling the hfs find init function as a temporary workaround until a patch is available.
For ext4dev-kmp-trace, restrict access to the package to minimize the risk of exploitation until a fix is provided.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Exploit
DoS
NULL Pointer Dereference
