CVE-2026-97436

A flaw was found in the Linux kernel's dpaa2-switch driver. When multiple network bridges are configured across ports on the same switch device, removing a port from a bridge fails to release its Forwarding Database FDB, which tracks network destination addresses. A privileged user modifying...

CVE-2026-97430

A flaw was found in the Linux kernel's USB eXtensible Host Controller Interface xHCI driver. When the host controller is inaccessible during power management operations, such as system suspend or resume, new commands are not properly prevented from being added to the command ring. A local user...

CVE-2026-97501

A flaw was found in the Linux kernel's MediaTek pin controller pinctrl driver, which can lead to a Denial of Service DoS. When configuring general-purpose input/output GPIO pin directions, the driver attempts to acquire a blocking lock while operating in an atomic context. A local attacker could...

CVE-2026-97426

A flaw was found in the Linux kernel's AMDGPU driver. When processing input for the SmartShift bias sysfs configuration interface, an input parsing failure causes the driver to release power management access without having first acquired it. A local user with write access to this interface could...

CVE-2026-97604

A flaw was found in the Linux kernel's virtual framebuffer vfb driver. A local user can trigger a race condition by requesting colormap data while simultaneously unbinding the driver, causing memory to be freed while still being copied to user space. This use-after-free flaw can lead to a system...

CVE-2026-97603

A flaw was found in the Linux kernel's idpf network driver. This flaw allows a local user with administrative privileges to cause a Denial of Service DoS through a kernel crash. The issue occurs because dynamic interrupt moderation DIM background tasks are not disabled before releasing queue vect...

CVE-2026-97600

A flaw was found in the Linux kernel's CC2520 radio driver. During device removal, an interrupt handler can queue background work after the driver's private data has been released, resulting in a use-after-free condition. A local user with privileges to disconnect or unbind the device could explo...

CVE-2026-97599

A flaw was found in the Linux kernel's IEEE 802.15.4 hardware simulator driver. A lack of proper locking allows concurrent channel updates to race against each other when modifying simulated device configuration parameters. A local user could exploit this flaw to cause a double-free memory...

CVE-2026-97502

A flaw was found in the Linux kernel's DaVinci MultiMediaCard MMC driver. When processing hardware interrupt events such as read timeouts or communication errors, the driver accesses a data pointer without verifying that an active transfer structure exists. A local user or abnormal device conditi...

CVE-2026-97435

A flaw was found in the Linux kernel's sja1105 network switch driver. When configuring traffic control redirect actions, the driver does not verify whether the destination port belongs to the local switch device. A local privileged user could exploit this flaw by configuring a cross-chip redirect...

CVE-2026-97434

A flaw was found in the Linux kernel's dpaa2-switch network driver. During device removal, network packet polling instances NAPI shared across switch ports can be deleted before they are properly disabled. A local user with administrative privileges could trigger this issue during device teardown...

CVE-2026-97433

A flaw was found in the Linux kernel's Non-Volatile Memory Express NVMe driver. When processing Flexible Data Placement FDP configuration log descriptors, the driver fails to properly validate descriptor sizes before iterating through them. A malicious NVMe device returning crafted log data can...

CVE-2026-97431

A flaw was found in the Linux kernel's AMD display driver. When updating display streams, the driver improperly handles phantom streams that have already been destroyed, triggering a null pointer dereference. A local attacker can trigger this issue during display power management operations,...

CVE-2026-97428

A flaw was found in the Linux kernel's AMDGPU driver. During the parsing of Field Replaceable Unit FRU data from EEPROM, the driver does not properly validate boundaries against the actual data length. An attacker capable of supplying truncated or malformed FRU data can trigger an out-of-bounds...

CVE-2026-97427

A flaw was found in the Linux kernel's AMD GPU power management driver. A local user with write access to the powerplay sysfs interface could trigger a heap-based buffer overflow by providing input data exceeding the allocated buffer size. This issue can lead to memory corruption, resulting in a...

CVE-2026-97414

A flaw was found in the Linux kernel's MediaTek audio driver. When suspending the audio device, the driver fails to verify whether memory allocation for the register backup buffer succeeded before accessing it. A local user capable of triggering power management operations during low-memory...

CVE-2026-97411

A flaw was found in the Linux kernel's IBM EMAC network driver. During module removal, the driver unconditionally attempts to disable network polling routines even if they were never enabled or were already stopped. This improper state handling causes the kernel to enter an infinite loop, resulti...

CVE-2026-97409

A flaw was found in the Linux kernel's NVMe over Fibre Channel NVMe-FC driver. When establishing a connection to an NVMe-FC target, an administrative request timeout triggers error-handling routines that attempt to abort requests on uninitialized I/O queues. A malicious or unresponsive target cou...
