NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-modules-core package and not the kernel-rt-64k-modules-core package as distributed by Rocky-Linux. See How to fix? for Rocky-Linux:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

ipv6: fix possible UAF in icmpv6_rcv()

Caching saddr and daddr before pskb_pull() is problematic since skb->head can change.

Remove these temporary variables:

  • We only access &ipv6_hdr(skb)->saddr and &ipv6_hdr(skb)->daddr when net_dbg_ratelimited() is called in the slow path.

  • Avoid potential future misuse after pskb_pull() call.
