CVE-2026-98554

The Linux kernel contains a vulnerability in the vlan component where certain callers (e.g., llc_alloc_frame() ) or skbs allocated before dynamic headroom changes can reach vlan_dev_hard_header() with insufficient headroom. This condition triggers a skb_under_panic() . The issue is addressed by u...

kernel: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

A flaw was found in the Linux kernel. A local attacker can exploit an out-of-bounds write vulnerability when the kernel recomputes an IPv6 Source Routing Header SRH. This issue occurs because insufficient headroom is reserved during the recompression process, leading to memory corruption...
