Record from OSV · Published November 4, 2025
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_pipapo: fix null deref for empty set Blamed commit broke the check for a null scratch map: - if (unlikely(!m || !*raw_cpu_ptr(m->scratch))) + if (unlikely(!raw_cpu_ptr(m->scratch))) This should have been "if (!*raw_ ...)". Use the pattern of the avx2 version which is more readable. This can only be reproduced if avx2 support isn't available.
