NVD Description

Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla 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.
