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: A vulnerability in the Linux kernel has been resolved, related to the bpf (Berkeley Packet Filter) functionality, specifically with ktls panic and sockmap. The issue arises when the BPF program executes certain functions, such as bpf msg push data(), which can increase the size of msg pl->sg, leading to errors when attempting to roll back to non-zero copy logic. This can cause the kernel to panic. The vulnerability is related to the handling of corking in non-zero-copy logic for TCP sockets.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
