Descriptions

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: core: Fix racing issue between ufshcd_mcq_abort() and ISR

If command timeout happens and cq complete IRQ is raised at the same time,
ufshcd_mcq_abort clears lprb->cmd and a NULL pointer deref happens in the
ISR. Error log:

ufshcd_abort: Device abort task at tag 18
Unable to handle kernel NULL pointer dereference at virtual address
0000000000000108
pc : [0xffffffe27ef867ac] scsi_dma_unmap+0xc/0x44
lr : [0xffffffe27f1b898c] ufshcd_release_scsi_cmd+0x24/0x114

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: ufs: core: soluciona el problema de ejecuciones entre ufshcd_mcq_abort() e ISR. Si se agota el tiempo de espera del comando y se genera cq complete IRQ al mismo tiempo, ufshcd_mcq_abort borra lprb->cmd y un La eliminación del puntero NULL ocurre en el ISR. Registro de errores: ufshcd_abort: tarea de cancelación del dispositivo en la etiqueta 18 No se puede manejar la desreferencia del puntero NULL del kernel en la dirección virtual 0000000000000108 pc: [0xffffffe27ef867ac] scsi_dma_unmap+0xc/0x44 lr: [0xffffffe27f1b898c] ufshcd_release_scsi_cmd+0x24 /0x114
