Vulnerability from github – Published: 2026-01-13 18:31 – Updated: 2026-01-19 15:30

Details

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

media: dvb-usb: dtv5100: fix out-of-bounds in dtv5100_i2c_msg()

rlen value is a user-controlled value, but dtv5100_i2c_msg() does not check the size of the rlen value. Therefore, if it is set to a value larger than sizeof(st->data), an out-of-bounds vuln occurs for st->data.

Therefore, we need to add proper range checking to prevent this vuln.
