Linux Distros Unpatched Vulnerability : CVE-2026-31742

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: vt: discard stale unicode buffer on alt screen exit after resize When enteraltscreen saves...

CVE-2026-31701

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA caiaq driver. This vulnerability arises from improper handling of Universal Serial Bus USB device references. When a USB device is disconnected, the driver may attempt to access memory that has already been freed, a...

CVE-2025-52347

An issue in the component DirectIo64.sys of PassMark BurnInTest v11.0 Build 1011, OSForensics v11.1 Build 1007, and PerformanceTest v11.1 Build 1004 allows attackers to access kernel memory and escalate privileges via a crafted IOCTL 0x8011E044 call...

CVE-2026-43048

A flaw was found in the Linux kernel's Human Interface Device HID core. An incorrect memset operation within the hidreportrawevent function can lead to out-of-bounds OOB reads and writes. This vulnerability occurs when the incoming event buffer size is insufficient to fill the associated report,...

CVE-2026-43044

A flaw was found in the Linux kernel's crypto: caam module. When processing HMAC Keyed-Hash Message Authentication Code keys longer than the block size, the memory allocated for the key copy was not correctly aligned for Direct Memory Access DMA operations. This oversight could lead to DMA...

CVE-2026-43042

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS module. This vulnerability is caused by a race condition where concurrent operations on network label data can lead to inconsistent memory access. This can result in out-of-bounds memory reads or writes, potentially causing...

CVE-2026-22167 GPU DDK - Cache resident PM buffers writable by other GPU requestors, leading to arbitrary write to physical memory

Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel an...

CVE-2026-43044

In the Linux kernel, the following vulnerability has been resolved: crypto: caam - fix DMA corruption on long hmac keys When a key longer than block size is supplied, it is copied and then hashed into the real key. The memory allocated for the copy needs to be rounded to DMA cache alignment, as...

CVE-2026-43044

The CVE-2026-43044 issue affects the Linux kernel's crypto: caam module. When processing HMAC keys longer than the block size, the copied key’s memory was not properly aligned for DMA, risking corruption of adjacent memory. The vulnerability’s root cause was the allocation of a copy that relied o...

EUVD-2026-26581

In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-adc161s626: use DMA-safe memory for spiread Add a DMA-safe buffer and use it for spiread instead of a stack memory. All SPI buffers must be DMA-safe. Since we only need up to 3 bytes, we just use a u8 instead of be16...
