| Subject: CVE-2024-27075: media: dvb-frontends: avoid stack overflow warnings with clang |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27075 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
