- Summary
- CVE-2025-40240 affecting package kernel for versions less than 6.6.117.1-1
- Details
-
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->headskb is not. Check for fraglist instead and do it just before replacing chunk->skb. We're sure that otherwise chunk->skb is non-NULL because of outer if() condition.
