CVSS v3.1
5.5
Medium
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to the bpf component of the Linux kernel, where the verifier assumes that the 'sk' field in 'struct socket' is valid and non-NULL when the 'socket' pointer itself is trusted and non-NULL. However, this assumption may not hold when a socket is just created and passed to the LSM socket accept hook. This can lead to a NULL pointer dereference, potentially causing a denial of service.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
