Linux Distros Unpatched Vulnerability : CVE-2026-89707

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nfsd: release path refs on followdown error nfsdcrossmnt initializes a local struct path with mntget and dget before calling followdown. On a negative return t...

CVE-2026-89453

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit driver for AMD. This vulnerability occurs when the system handles certain memory access errors, specifically Page Request PPR faults, without properly releasing a reference to a PCI device. This oversight causes a...

CVE-2026-89715

A flaw was found in the Linux kernel's NFS/localio component. A race condition during file handling can lead to a reference leak, where system resources are not properly released. This continuous accumulation of unreleased references can exhaust available resources, preventing network namespace...

CVE-2026-89683

A flaw was found in the Linux kernel's nfsd NFS daemon. A remote attacker could exploit this vulnerability by sending a specially crafted NFSv3 filehandle targeting a V4ROOT export's file system identifier fsid. This action triggers a dentry reference leak, which can lead to resource exhaustion a...

CVE-2026-89473

A flaw was found in the Linux kernel's bq25890 power supply driver. The bq25890fwprobe function acquires a reference to a secondary charger but fails to release it on subsequent probe failures or driver detach. This reference leak can lead to resource exhaustion over time, potentially allowing a...

CVE-2026-89447

A flaw was found in the Linux kernel's iommufd subsystem. A local attacker could exploit a vulnerability where an object reference is leaked during the unmapping of internal accesses. This occurs because the iommufdaccessnotifyunmap function incorrectly locks an object before checking if the acce...

CVE-2026-89512

A flaw was found in the Linux kernel's remoteproc SCP component. This vulnerability involves a device reference leak, where the system fails to properly release a reference to a device during a driver data lookup. This occurs specifically before the driver has been fully bound. A local attacker...

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix dentry ref leak on V4ROOT export filehandle lookup nfsdsetfhdentry leaks the dentry reference from exportfsdecodefhraw when the NFS3FHSIZE or NFSFHSIZE switch cases detect NFSEXPV4ROOT and goto out. The out: label calls...

CVE-2026-89688

In the Linux kernel, the following vulnerability has been resolved: nfsd: drop the stateid, not the stateowner, on seqidop replay retry In nfs4preprocessseqidop the stateid is obtained from nfsd4lookupstateid, which holds a reference on the nfs4stid sccount but takes no reference on the stateowne...
