CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel's batman-adv module, specifically in the batadv_get_vid() function, which fails to verify the accessibility of the ethernet header's proto field before accessing it. This oversight can lead to potential out-of-bounds memory access, posing a risk of system instability or exploitation. Linux system administrators and developers utilizing the batman-adv module should prioritize addressing this issue to mitigate potential security risks.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: batman-adv: dat: ensure accessible eth_hdr proto field When batadv_get_vid() accesses the proto field of the ethernet header, it is not checking if the data itself is accessible. The caller is responsible for it. But in contrast to other call sites, batadv_dat_get_vid() and its caller didn't make sure this is true. This could have caused an out-of-bounds access.
