CVE-2026-80601

A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module of the Linux kernel. When the pskbmaypull function is called by batadvgetvid, it can reallocate the buffer, causing variables to point to a freed memory region. This use-after-free vulnerability could...

CVE-2026-80599

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module. An attacker, by sending specially crafted network packets, could trigger an out-of-bounds memory access in the batadvgetvid function. This occurs because the function fails to verify t...
