Descriptions
In the Linux kernel, the following vulnerability has been resolved:
nvmet-tcp: Fix a kernel panic when host sends an invalid H2C PDU length
If the host sends an H2CData command with an invalid DATAL,
the kernel may crash in nvmet_tcp_build_pdu_iovec().
Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000000
lr : nvmet_tcp_io_work+0x6ac/0x718 [nvmet_tcp]
Call trace:
process_one_work+0x174/0x3c8
worker_thread+0x2d0/0x3e8
kthread+0x104/0x110
Fix the bug by raising a fatal error if DATAL isn't coherent
with the packet size.
Also, the PDU length should never exceed the MAXH2CDATA parameter which
has been communicated to the host in nvmet_tcp_handle_icreq().
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nvmet-tcp: soluciona un pánico del kernel cuando el host envía una longitud de PDU H2C no válida. Si el host envía un comando H2CData con un DATAL no válido, el kernel puede fallar en nvmet_tcp_build_pdu_iovec(). No se puede manejar la desreferencia del puntero NULL del kernel en la dirección virtual 0000000000000000 lr: nvmet_tcp_io_work+0x6ac/0x718 [nvmet_tcp] Rastreo de llamadas: Process_one_work+0x174/0x3c8 trabajador_thread+0x2d0/0x3e8 kthread+0x104/0x110 Solucione el error generando un error fatal si DATAL es No es coherente con el tamaño del paquete. Además, la longitud de la PDU nunca debe exceder el parámetro MAXH2CDATA que se ha comunicado al host en nvmet_tcp_handle_icreq().
