Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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 'stv0367ter_set_frontend' [-Werror,-Wframe-larger-than] 1214 | static int stv0367ter_set_frontend(struct dvb_frontend *fe) Rework the stv0367_writereg() function to be simpler and mark both register access functions as noinline_for_stack so the temporary i2c_msg structures do not get duplicated on the stack when KASAN_STACK is enabled.

Recommended fix High confidence

Linux Kernel >= 4.19.311

  1. Apply the kernel patch from commit 107052a8cfeff3a97326277192b4f052e4860a8a which marks stv0367_writereg() and stv0367_readreg() as noinline_for_stack to prevent stack frame size from exceeding the 2048 byte limit
  2. Alternatively, upgrade the Linux kernel to version 4.19.311 or later where this fix is incorporated
