kernel: nfsd: cancel nfsd_shrinker_work using sync mode in nfs4_state_shutdown_net

In the Linux kernel, the following vulnerability has been resolved: nfsd: cancel nfsdshrinkerwork using sync mode in nfs4stateshutdownnet In the normal case, when we excute echo 0 /proc/fs/nfsd/threads, the function nfs4statedestroynet in nfs4stateshutdownnet will release all resources related to...

The vulnerability of the nfs4_state_shutdown_net() function in the fs/nfsd/nfs4state.c module of the nfsd component of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the nfs4stateshutdownnet function in the fs/nfsd/nfs4state.c module of the nfsd component of the Linux operating system is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...
