CVE-2026-80599

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> batman-adv: dat: ensure accessible eth_hdr proto field<br /> <br /> When batadv_get_vid() accesses the proto field of the ethernet header, it<br /> is not checking if the data itself is accessible. The caller is responsible<br /> for it. But in contrast to other call sites, batadv_dat_get_vid() and its<br /> caller didn&amp;#39;t make sure this is true. This could have caused an<br /> out-of-bounds access.
