Linux kernel media driver Write TS to Decoder

The vulnerability of the writetstodecoder function in the drivers/staging/media/av7110/av7110av.c file, a driver for preparing media data in the Linux operating system, is related to the execution of operations outside of the buffer in memory. Exploiting this vulnerability could allow an attacker...

CVE-2023-54284 media: av7110: prevent underflow in write_ts_to_decoder()

In the Linux kernel, the following vulnerability has been resolved: media: av7110: prevent underflow in writetstodecoder The buf4 value comes from the user via tsplay. It is a value in the u8 range. The final length we pass to av7110ipackinstantrepack is "len - buf4 + 1 - 4" so add a check to...

CVE-2023-54284

CVE-2023-54284 : Linux kernel vulnerability in the media/av7110 path. The issue arises from underflow-prone length calculation in write_ts_to_decoder(), where buf[4] is user-controlled via ts_play(). The intended final length passed to av7110_ipack_instant_repack() is computed as len - (buf[4] + ...
