NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-devel-matched package and not the kernel-64k-devel-matched package as distributed by AlmaLinux.

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

sctp: avoid NULL dereference when chunk data buffer is missing

chunk->skb pointer is dereferenced in the if-block where it's supposed to be NULL only.

chunk->skb can only be NULL if chunk->head_skb is not. Check for frag_list instead and do it just before replacing chunk->skb. We're sure that otherwise chunk->skb is non-NULL because of outer if() condition.
