| 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 6.6.74
Description
A potential out-of-bound access issue has been identified in the Linux kernel, specifically in the
fill frame info() function. This issue can be triggered by sending a packet with 14 bytes, pretending to be a VLAN packet. The fill frame info() function relies on skb->mac len, and the check has been extended to cover this case. The issue is related to an uninit-value in fill frame info() and hsr forward skb().Recommendations
Update to Linux kernel version 6.6.74 or later to resolve the issue. As a temporary workaround, consider restricting access to the vulnerable
fill frame info() function until a patch is available.Exploit
