CVE-2026-98841: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: virt: vmgenid: set driverdata before registering notification handlers Both probe paths register their notification handler before assigning driverdata, which the handler dereferences. In the devicetree path, the notification IRQ...

PT-2026-117031

In the Linux kernel, the following vulnerability has been resolved: net/mctp: publish the mctp dev only after it is initialised mctp add dev links the new mctp dev into dev-mctp ptr before mdev-dev is assigned, so a reader that picks the device up in that window dereferences a net device pointer...

CVE-2026-98854: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: of/overlay: only treat a positive changeset id as registered ofoverlayfdtapply stores the idralloc return value in ovcs-id before checking it. On failure the stored id is negative, freeoverlaychangeset's "if ovcs-id" check passes...

Linux Distros Unpatched Vulnerability : CVE-2026-98753

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tty: ttyport: restore TTYIOERROR on activation failure Make sure to restore the TTYIOERROR flag if activation fails to prevent I/O attempts on a port that is go...

PT-2026-117040

In the Linux kernel, the following vulnerability has been resolved: block: reject polled dio with user integrity metadata IOCB HAS METADATA leaves iocb-private as a uio meta, while iocb bio iopoll expects a bio. Since 2729a60bbfb9, metadata I/O always uses blkdev direct IO, which never publishes...

CVE-2026-98747: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: serial: core: fix NULL pointer dereference in serialcoreunregisterport port-portdev is NULL when no port device is installed: it is cleared on teardown, and never set if registration failed before serialcoreportdeviceadd...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.5 contains a security vulnerability. This vulnerability stems from the fact that in serialcoreunregisterport, when port-portdev is empty, the function passes it without checking, leading to a null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.11 contains security vulnerabilities. These vulnerabilities arise from the failure to reset the numnapi count when releasing the napi vector, resulting in null pointer dereferencing within the kernel...

Linux Kernel Security Vulnerabilities

The Linux kernel version 7.0 contains a security vulnerability. This vulnerability stems from the fact that the datcondsetstoragekey function in KVM s390 does not check the NULL oldkey passed by the caller. As a result, when the pagecondsetstoragekey function is called, a null pointer dereferenci...

Linux Kernel Security Vulnerabilities

The Linux kernel versions 5.10.266 to 5.11, 5.15.217 to 5.16, and 7.2 contain security vulnerabilities. These vulnerabilities stem from a race condition between the tbremovework and tbdomainremove functions in the Thunderbolt driver. The tbfreeunpluggedxdomains function is called without checking...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.8 contains security vulnerabilities. These vulnerabilities stem from the failure to check the CQE during the removal of the XSK TX queue. This could result in a NULL CQE being passed to the mlx5exskfilltimestamp function, leading to a null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.18 contains a security vulnerability. This vulnerability arises from passing NULL as a register address during register registration for the divided clock. The Common Clock Framework calls clkdividerrecalcrate, which dereferences that address via readl. As a result, the...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.17 contains a security vulnerability. This vulnerability arises from the fact that when setting the Rx coalesce parameters before the interface is initially opened, the bcmgenetsetrxcoalesce function accesses ring-priv which points to NULL. This leads to a null pointer...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.15 contains a security vulnerability. This vulnerability stems from the ofoverlayfdtapply function in of/overlay, which checks the return value of idralloc before execution. If this function fails, a negative ID passes the check, and uninitialized ovcs-ovcslist is...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.4 contains a security vulnerability. This vulnerability stems from the second PCI function detection in cdns3pciprobe, where pcigetdrvdata returns NULL. Subsequently, the assignment of wrap-devfn results in a null pointer dereferencing, which may lead to a kernel crash...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises when the user space provides full-speed descriptors, and FunctionFS runs at a higher speed. In this case, the FUNCTIONFSENDPOINTDESC ioctl only selects the endpoint descriptor at the current speed, without retreating to...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.0 contains security vulnerabilities. These vulnerabilities stem from the failure to check whether dcsink is empty during MST mode validation. The functions dmdpmstisportsupportmode and getconvfrlbw access dcsink that has been asynchronously cleared, which may lead to nu...

Linux Kernel Security Vulnerabilities

There are security vulnerabilities in Linux kernels versions from 5.10.258 to 5.11, from 5.15.165 to 5.16, from 6.1.105 to 6.2, from 6.6.46 to 6.7, from 6.10.5 to 6.11, and version 6.11. The vulnerability arises from the failure of the dcstatecreatecopy function to return a value, resulting in NU...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.18 contains security vulnerabilities. These vulnerabilities arise from the failure to return values when PTP is not in use. During the unbinding of drivers, the uninitialized txskbs queue is cleaned up, leading to null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.6 contains a security vulnerability. This vulnerability arises from the mtkethsoc driver, which allocates a dummy netdev after registering the MAC netdev and adds shared NAPIs. This results in a null pointer derefrence when network devices become visible prematurely,...
