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().
