Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak issue has been identified in the Linux kernel, specifically in the nfsd component. The leak occurs when the
nfsd4 run cb function fails to queue dl recall, resulting in an unreferenced object and a memory leak. This issue is related to the nfs4 stid reference count not being decremented properly after the corresponding work struct is processed. Technical details about the issue include the nfsd4 process open1, nfsd4 open, and nfsd4 proc compound functions being involved in the leak.Recommendations
To resolve this issue, it is recommended to check the result of
nfsd4 run cb and call nfs4 put stid if the call to nfsd4 run cb fails to queue dl recall. This will ensure that the nfs4 stid reference count is properly decremented and the memory leak is fixed.Exploit
