Subject: [PATCH 0/1] media: dvb-usb-v2: ce6230: fix syzkaller bug
Date: Wed, 22 Apr 2026 21:26:43 +0200 [thread overview]
Message-ID: <20260422192644.21814-1-jakovnovak30@gmail.com> (raw)
This patch fixes a syzkaller bug which was reported in the usb core
after sending a urb_control_msg. The main problem that caused this was
the ce6230_ctrl_msg function trying to send a read control message of
size 0, which then caused the system to panic after. The solution was to
add a check in this function to check if the message has a greater than
zero size before sending it, otherwise we log the error and return.
