| Vetor | 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 versions prior to 4.14
Description
The issue is related to the sctp do peeloff function in the Linux kernel, which does not properly check the intended netns during a peel-off action. This can lead to a denial of service, causing a system crash due to a use-after-free error. Local users can exploit this by making crafted system calls, potentially resulting in unspecified other impacts.
Recommendations
For Linux kernel versions prior to 4.14, update to version 4.14 or later to resolve the issue. As a temporary workaround, consider restricting access to the sctp do peeloff function to minimize the risk of exploitation.
