CVE-2025-21758

CVE-2025-21758 is a Linux kernel vulnerability in the IPv6 multicast path. The issue: mld_newpack() could be called without RTNL or RCU being held, which may lead to unsafe access. The fix replaces sock_alloc_send_skb() (which uses GFP_KERNEL and can sleep) with alloc_skb() and charges the net-&g...

CVE-2021-47146

CVE-2021-47146 concerns the Linux kernel where mld_newpack could panic when headroom is large because high-order page allocation was disallowed (skb_put() path). The issue is triggered during IPv6 multicast handling in mld_newpack/mld_send_initial_cr and can lead to a kernel crash; the provided t...
