| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A potential null-pointer dereference exists in the
snd hdac regmap sync() function due to a data race condition. The codec->regmap variable, often protected by codec->regmap lock, can be accessed without holding the lock. If codec->regmap is set to NULL immediately after the condition is checked, a null-pointer dereference may occur within the regcache sync() function. The fix extends mutex lock coverage to protect the conditional statement and the call to regcache sync().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
