CVE-2026-98287

The Linux kernel contains a vulnerability in the pppoatm component where the pppoatm_send() function fails to ensure the skb header is writable when performing LLC encapsulation. While standard packets use skb_cow_head(), packets arriving via PPP channel bridging (PPPIOCBRIDGECHAN) bypass this ch...
