In the Linux kernel, the following vulnerability has been resolved:
media: dvb-frontends: avoid stack overflow warnings with clang
A previous patch worked around a KASAN issue in stv0367, now a similar problem showed up with clang:
drivers/media/dvb-frontends/stv0367.c:1222:12: error: stack frame size (3624) exceeds limit (2048) in 'stv0367tersetfrontend' [-Werror,-Wframe-larger-than] 1214 | static int stv0367tersetfrontend(struct dvb_frontend *fe)
Rework the stv0367writereg() function to be simpler and mark both register access functions as noinlineforstack so the temporary i2cmsg structures do not get duplicated on the stack when KASAN_STACK is enabled.
