CVE-2025-38302
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: block: don't use submit_bio_noacct_nocheck in blk_zone_wplug_bio_work Bios queued up in the zone write plug have already gone through all all preparation in the submit_bio path, including the freeze protection. Submitting them through submit_bio_noacct_nocheck duplicates the work and can can cause deadlocks when freezing a queue with pending bio write plugs. Go straight to ->submit_bio or blk_mq_submit_bio to bypass the superfluous extra freeze protection and checks.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bloque: no usar submit_bio_noacct_nocheck en blk_zone_wplug_bio_work. Las BIOS en cola en el complemento de escritura de zona ya han pasado por toda la preparación en la ruta submit_bio, incluida la protección contra congelamiento. Enviarlas mediante submit_bio_noacct_nocheck duplica el trabajo y puede causar interbloqueos al congelar una cola con complementos de escritura de BIOS pendientes. Vaya directamente a ->submit_bio o blk_mq_submit_bio para omitir la protección contra congelamiento y las comprobaciones adicionales innecesarias."
