Linux Kernel Security Vulnerabilities

The Linux kernel version 6.10 contains security vulnerabilities. These vulnerabilities stem from the vmgenid driver, which does not set the driverdata before registering the notification handler. When an interrupt occurs, the handler dereferes a null pointer, which may lead to kernel crashes...

Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.33 contains security vulnerabilities. These vulnerabilities arise from the failure to restore the TTYIOERROR flag when the ttyport is activated. This can lead to I/O attempts when the port has disappeared or during power failures. When the TTY ioctl competes with...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.10 contains a security vulnerability. This vulnerability arises from pfcpnewlink creating a UDP socket before registernetdevice. After the registration fails, the socket is released repeatedly through an erroneous path, resulting in a null pointer dereference...

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,...

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 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 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 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

The Linux kernel version 4.18 contains a security vulnerability. This vulnerability stems from the s390/cio subsystem, where the ccwdevicegetutilstr function does not check the return value of chpidtochp, which may lead to null pointer dereferencing...

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 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 has a security vulnerability. This vulnerability stems from the EDAC/altera driver, which marks the setup callback and auxiliary functions of a10 EDAC as init. These functions may execute after memory release during the probe path, resulting in the dereferencing of already releas...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.15 contains a security vulnerability. This vulnerability stems from the mctpadddev function, which links the new mctpdev to dev-mctpptr before assigning the value to mdev-dev. When a reader accesses the device during this period, it may dereference a netdevice pointer...

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 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 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...

cups: Fix of 2 CVEs

CVE-2026-107885: fix denial of service by not letting an in-flight Send-Document suppress submission timeouts of unrelated held jobs beyond MultipleOperationTimeout - CVE-2026-107890: fix cupsd NULL pointer dereference caused by repeated IPP group tags in job creation requests...

Linux Distros Unpatched Vulnerability : CVE-2026-57486

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, ixmlNodecompare in ixml/src/node.c passes the nullable nodeValue,...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference through the ValidateResponse process when a response header is declared with content instead of schema. An attacker can cause a process crash by sending a request to an affected endpoint, resulting in a nil...
