CVE-2026-89668

CVE-2026-89668 affects the nfsd (NFS daemon) component of the Linux kernel . In init_nfsd(), nfsd_debugfs_init() is called before nfsd4_init_slabs(). If the slab allocation fails, the early return bypasses nfsd_debugfs_exit(), leaving orphaned debugfs files with stale fops pointers into freed mod...

CVE-2026-89636 smb: client: clear ce->tgthint in free_tgts()

In the Linux kernel, the following vulnerability has been resolved: smb: client: clear ce-tgthint in freetgts When freetgts frees all structures in ce-tlist, ce-tgthint is left pointing to one of the freed cachedfstgt structures. If ce-tgthint is not reset before it is used later, it results in a...
