What is CVE-2026-68476?
A vulnerability has been resolved in the Linux kernel's IPVS module. The __ip_vs_get_out_rt() function may use a stale pointer to the IP header after calling skb_ensure_writable(), which can reallocate the buffer, leading to potential memory corruption. Updating the kernel is recommended.
