CVSS v3.1
5.5
Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.17.10
Description
The issue is related to the
input set capability() function in the Linux kernel, which can lead to an uncontrolled consumption of resources. An attacker can exploit this to cause a denial of service (panic) because input set capability() mishandles the situation in which an event code falls outside of a bitmap.Recommendations
For Linux kernel versions prior to 5.17.10, update to version 5.17.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the
input set capability() function to minimize the risk of exploitation.Fix
DoS
Buffer Overflow
Improper Resource Release
Resource Exhaustion
Improper Handling of Exceptional Conditions
