kernel: drm/amdgpu: zero-initialize GART table on allocation

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. When allocating a Graphics Address Remapping Table GART, the memory was not properly initialized. This could allow a local attacker to potentially access uninitialized memory, leading to information disclosure or unexpected system...

kernel: drm/amd/display: Use krealloc_array() in dal_vector_reserve()

A flaw was found in the Linux kernel's drm/amd/display component. The dalvectorreserve function calculates memory allocation size using 32-bit arithmetic, which can lead to an integer overflow. This overflow causes a smaller memory buffer to be allocated than intended, resulting in a heap overflo...

A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from...

kernel: drm/amd/display: Clamp VBIOS HDMI retimer register count to array size

A flaw was found in the Linux kernel's AMD display driver. This vulnerability occurs when the driver processes malformed VBIOS Video Basic Input/Output System data. Specifically, unvalidated register counts in the VBIOS can lead to an out-of-bounds memory write during the driver's initialization...

kernel: mm/slub: avoid accessing metadata when pointer is invalid in object_err()

A flaw was found in the Linux kernel’s SLUB memory allocator mm/slub. The function objecterr — used for debugging object metadata freelist pointer, redzone, etc. — can access invalid pointers when reporting corruption, leading to a crash. In some cases, due to freelist corruption e.g., detected b...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

CVE-2026-74442

A flaw was found in the Linux kernel's drm/vmwgfx driver. This vulnerability occurs when the vmwvkmsinit function fails to initialize a workqueue, leaving a pointer as NULL. During module unload, the vmwvkmscleanup function attempts to destroy this NULL workqueue, leading to a kernel panic. A loc...

CVE-2026-72277

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for ARM64 systems. When KVM constructs an L1 VNCR Virtual Nested Control Register mapping, it incorrectly applies cacheable memory attributes even when the underlying physical memory is not normal memory. This can lead to a...

CVE-2026-72259

A flaw was found in the Linux kernel's ASoC Audio System on Chip Mediatek MT8192 audio driver. This vulnerability occurs because the driver fails to release reserved memory after a successful assignment during the probe process. This oversight can lead to a memory leak, potentially causing system...

CVE-2026-68474

A flaw was found in the Linux kernel, specifically within the powerpc/spufs component responsible for managing memory access. This vulnerability allows for an out-of-bounds memory access due to incorrect boundary checks in the spufsmemmmapaccess function. An attacker could exploit this to corrupt...

CVE-2026-68473

A flaw was found in the Linux kernel's powerpc/uaccess component. The maskuseraddress function incorrectly checks for CONFIGE500 instead of CONFIGPPCE500. This error prevents the maskuseraddressisel function from being used on PowerPC E500 hardware, which could lead to improper handling of user...

CVE-2026-68472

A flaw was found in the Linux kernel's cfg80211 Wi-Fi subsystem. A remote attacker, by operating a malicious Access Point AP, could send a specially crafted EHT Multi-Link Element MLE in an MBSSID beacon. This could cause the kernel to read beyond the intended memory boundary when processing the...

CVE-2026-68471

A flaw was found in the Wi-Fi IEEE 802.11 component of the Linux kernel. The ieee80211mlecommonsize function uses the first common-info octet as the length for all known MLE Management Link Establishment types. However, the ieee80211mlesizeok function did not properly validate this length for all...

CVE-2026-68468

A flaw was found in the mtd: virt-concat component of the Linux kernel. When a virtual concatenated device is already registered, the mtdvirtconcatcreatejoin function generates a duplicate name but fails to free the newly allocated string. This oversight leads to a memory leak, which could...

CVE-2026-68467

A flaw was found in the Linux kernel's mtd: mchp23k256 driver. This driver, responsible for managing memory technology devices MTD, incorrectly determined the capabilities of certain SPI Serial Peripheral Interface flash chips. This could lead to the system misinterpreting the memory device's...

CVE-2026-74561

A flaw was found in the Linux kernel, specifically within its nexthop component responsible for network routing. A timing issue, known as a race condition, allows the system to access memory after it has been freed. This occurs when the kernel attempts to flush its routing cache while other...

CVE-2026-74519

A flaw was found in the Linux kernel. An issue within the pinctrl subsystem's device tree handling could lead to a double-free vulnerability. This occurs when an error path during device binding attempts to free uninitialized memory, potentially allowing a local attacker to trigger a system crash...

CVE-2026-74511

A flaw was found in the Linux kernel's Bluetooth management component. A race condition exists during Extended Inquiry Response EIR updates when the MGMTOPSETLOCALNAME operation is processed concurrently with modifications to the UUID list. This can lead to a use-after-free vulnerability in the...
