CVSS v3.1

5.5

Medium

VectorAV: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 (affected versions not specified)
Description The issue is related to a memory leak in the Linux kernel's ipv6 component, specifically in the seg6 hmac init algo function. This function returns without cleaning up previous allocations if one fails, leading to a memory leak and potential denial of service. The vulnerability can be exploited to cause a denial of service.
Recommendations Update the Linux kernel to a version that includes the fix for the memleak in seg6 hmac init algo. As a temporary workaround, consider disabling the seg6 hmac init algo function until a patch is available. Restrict access to the ipv6 component to minimize the risk of exploitation.
