Description
In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: Fix copy buffer page size
For non-registered buffer, fastrpc driver copies the buffer and
pass it to the remote subsystem. There is a problem with current
implementation of page size calculation which is not considering
the offset in the calculation. This might lead to passing of
improper and out-of-bounds page size which could result in
memory issue. Calculate page start and page end using the offset
adjusted address instead of absolute address.
Affected configurations
• linux linux kernel (>= 5.2 < 6.1.129)
• linux linux kernel (>= 6.2 < 6.6.78)
• linux linux kernel (>= 6.7 < 6.12.14)
• linux linux kernel (>= 6.13 < 6.13.3)
