  3. CVE-2025-38120
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_set_pipapo_avx2: fix initial map fill If the first field doesn't cover the entire start map, then we must zero out the remainder, else we leak those bits into the next match round map. The early fix was incomplete and did only fix up the generic C implementation. A followup patch adds a test case to nft_concat_range.sh.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nf_set_pipapo_avx2: corrección del relleno inicial del mapa. Si el primer campo no cubre todo el mapa inicial, debemos poner a cero el resto; de lo contrario, filtraremos esos bits al mapa de la siguiente ronda de coincidencia. La corrección inicial estaba incompleta y solo corrigió la implementación genérica de C. Un parche posterior añade un caso de prueba a nft_concat_range.sh.
