Description
A vulnerability was found in the xfrm module in the Linux Kernel. This issue was discovered during fuzz testing, where uninitialized memory containing potentially sensitive data was inadvertently copied to user-space. This issue occurs when dumping IPsec algorithm data structures, exposing random padding from the structures. This issue could lead to information leaks if uninitialized memory is accessed by user-space applications.
Statement
This vulnerability is considered moderate severity. While it involves the leakage of uninitialized kernel memory, it requires specific conditions to be exploited. The information leaked consists of random padding within data structures, which is less likely to contain critical information compared to more sensitive kernel data, such as encryption keys or user credentials.
CVSS score applicability
The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
