Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: batman-adv: Access to unicastttvnskb-data is only possible after skb realloc. The pskbmaypull function called by batadvgetvid could reallocate the buffer behind the skb. Variables that pointed to the old buffer need to be...

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...
