Descriptions

In the Linux kernel, the following vulnerability has been resolved: scsi: target: pscsi: Fix bio_put() for error case As of commit 066ff571011d ("block: turn bio_kmalloc into a simple kmalloc
wrapper"), a bio allocated by bio_kmalloc() must be freed by bio_uninit()
and kfree(). That is not done properly for the error case, hitting WARN and
NULL pointer dereference in bio_free().

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: target: pscsi: corrige bio_put() para el caso de error A partir del commit 066ff571011d ("bloque: convierte bio_kmalloc en un contenedor kmalloc simple"), una biografía asignada por bio_kmalloc() debe ser liberado por bio_uninit() y kfree(). Esto no se hace correctamente en el caso de error, al presionar WARN y desreferenciar el puntero NULL en bio_free().
