CVE-2026-89646

A flaw was found in the Ceph filesystem component of the Linux kernel. When a writeback operation is aborted during an unmount process, a reference to an inode a data structure describing a filesystem object is not properly released. This prevents the inode from being evicted, potentially leading...

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...

CVE-2026-89715

In the Linux kernel, the following vulnerability has been resolved: NFS/localio: fix ref leak on nfsuuidaddfile failure When nfsuuidaddfile races with nfsuuidput tearing down uuid-net, it returns -ENXIO without publishing nfl-nfsuuid via rcuassignpointer. nfsopenlocalfh then enters its error bran...

CVE-2026-89683

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...

CVE-2026-89681

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix layout fence worker double-reference race The workqueue core clears WORKSTRUCTPENDING before the callback is invoked, so delayedworkpending in lmbreakertimedout can return false while the fence worker is already running...

CVE-2026-89645

In the Linux kernel, the following vulnerability has been resolved: btrfs: drop recovered reloc root refs on recovery failure During relocation recovery, each fs root gets a reference to its relocation root. If loading or adding a later root fails, or if the first transaction commit fails,...

CVE-2026-89646

In the Linux kernel, the following vulnerability has been resolved: ceph: fix leaked inode reference on writeback abort at umount cephdirtyfolio takes a wrbuffer claim on each newly dirtied folio: it bumps iwrbufferref taking an ihold on the 0-1 transition and attaches the snapcontext to...

CVE-2026-89590

In the Linux kernel, the following vulnerability has been resolved: accel/rocket: Fix error path handling in rocketjobrun In rocketjobrun, after taking an extra fence reference for job-donefence via dmafenceget, the error paths have three bugs: - The dmafence reference held by job-donefence is...

CVE-2026-89512

In the Linux kernel, the following vulnerability has been resolved: remoteproc: scp: Fix device reference leak on failed lookup Make sure to drop the reference taken to the SCP device when attempting to look up its driver data before the driver has been bound. Note that holding a reference to a...

CVE-2026-89473

In the Linux kernel, the following vulnerability has been resolved: power: supply: bq25890: Fix powersupply reference leak bq25890fwprobe acquires a reference to a secondary charger using powersupplygetbyname, but the reference is not released on later probe failures or on driver detach. In...

CVE-2026-89446

In the Linux kernel, the following vulnerability has been resolved: iommufd: Release current IOAS on xastore failure iommufdtakealliovarwsem takes an object reference and the iovarwsem write lock before storing the IOAS in the temporary ioaslist xarray. If xastore fails, the current IOAS has not...

CVE-2026-89453

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Put PCI device after handling PPR faults iommucalliopfnotifier looks up the requester with pcigetdomainbusandslot, which returns a PCI device with its reference count incremented. Neither the successful...

CVE-2026-89447

In the Linux kernel, the following vulnerability has been resolved: iommufd: Avoid locking internal accesses during unmap iommufdaccessnotifyunmap skips internal accesses because they do not have an external unmap callback to invoke.

CVE-2026-89715

CVE-2026-89715 is a reference leak in the Linux kernel NFS/localio subsystem. When nfs_uuid_add_file() races with nfs_uuid_put() tearing down uuid->net, it returns -ENXIO without publishing the RCU pointer. The error path in nfs_open_local_fh() then leaks a caller-owned nfsd_file reference (pi...
