CVSS 3.1
9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2026-80600
Critical (9.8). EPSS 0.7% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: dat: acquire ARP hw source only after skb realloc
The pskb_may_pull() called by batadv_get_vid() could reallocate the buffer
behind the skb. Variables which were pointing to the old buffer need to be
reassigned to avoid an use-after-free.
