After an update of my system, mythbackend repeatedly failed to start: no
obvious error messages, it just stalls. The update included security
patches to the 5.14.21 kernel. Amongst those, I found:
- CVE-2022-45886: Fixed a .disconnect versus dvb_device_open race
condition in dvb_net.c that lead to a use-after-free (bsc#1205760).
- CVE-2022-45885: Fixed a race condition in dvb_frontend.c that could
cause a use-after-free when a device is disconnected (bsc#1205758).
- CVE-2022-45887: Fixed a memory leak in ttusb_dec.c caused by the lack
of a dvb_frontend_detach call (bsc#1205762).
- CVE-2022-45919: Fixed a use-after-free in dvb_ca_en50221.c that could
occur if there is a disconnect after an open, because of the lack of a
wait_event (bsc#1205803).
- CVE-2022-45884: Fixed a use-after-free in dvbdev.c, related to
dvb_register_device dynamically allocating fops (bsc#1205756).
- CVE-2023-31084: Fixed a blocking issue in
drivers/media/dvb-core/dvb_frontend.c (bsc#1210783).
These may have nothing to do with the problem, but are at least in an
area that could affect MythTV. Reverting back to an earlier disc
snapshot has worked as a temporary fix.
I'm mainly wondering if anyone else on here has run into similar.
I'm using OpenSuSE Leap 15.4. It may be specific to that distro, but I
assume these patches will make there way to other distros.
