A vulnerability in the Linux kernel's media subsystem for dvb-usb devices using the dtv5100 driver allows an out-of-bounds write due to improper validation of a user-controlled length value in the dtv5100_i2c_msg() function. This can lead to memory corruption. The issue arises because the rlen parameter is not checked against the size of the destination buffer, st->data. A fix has been implemented to add proper range checking to prevent this vulnerability. Join the discussion | GCVE Database | 01/13/2026, 18:31:04 UTC Added: 07/30/2026, 15:50:41 UTC |
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.
