CVE-2026-98144

A flaw was found in the Linux kernel's AMD XDNA accelerator driver. A local user could cause a denial of service DoS by triggering a resource leak during command error handling. By manipulating buffer handles and importing an unmappable memory buffer object BO, an attacker can cause buffer mappin...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nilfs2: A bug has been fixed where nilfsgetblock returns a successful status when searching for and inserting the specified block both times fail inconsistently. If this inconsistent behavior is not due to a previously fixed bug,...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: pstore: ramcore: Fixed an issue where an incorrect success return occurred when vmap failed. In persistentramvmap, vmap might return NULL upon failure. If the offset is non-zero, adding offsetinpagestart causes the function to...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: erofs: Fix for lz4 inplace decompression Currently, EROFS can map another compressed buffer for inplace decompression, which was used to handle cases where some pages of compressed data are not actually in-place I/O. However, lik...

ALPINE-CVE-2025-58151

varstored is a component of the Xapi toolstack handling UEFI Variables for a VM. It has a communication path with OVMF inside the VM involving mapping a buffer prepared by OVMF. Within varstored, there were insufficient compiler barriers, creating TOCTOU issues with data in the shared buffer. The...

PT-2026-55985

Name of the Vulnerable Software and Affected Versions The product name cannot be determined affected versions not specified Description Memory corruption occurs when invoking device input/output control operations for mapping and unmapping persistent memory buffers. This issue is caused by improp...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Shmem writes are flushed before mapping buffers with cached mappings. The shmem layer zeroes out new pages using cached mappings. If we do not flush these writes using the CPU, we might leave dirty cachelines behind,...

CVE-2026-46312

A flaw was found in the videobuf2 subsystem of the Linux kernel. The vb2dmasgmmap function did not correctly set Virtual Memory Area VMA flags, specifically VMDONTEXPAND and VMDONTDUMP. This oversight could lead to a kernel warning and system crash when mapping an imported Direct Memory Access DM...

EUVD-2026-32374

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix memory leak in amdxdnaubufmap The amdxdnaubufmap function allocates memory for sg and internal sg table structures, but it fails to free them if subsequent operations sgalloctablefrompages or dmamapsgtable fail...

CVE-2026-45908 accel/amdxdna: Fix memory leak in amdxdna_ubuf_map

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix memory leak in amdxdnaubufmap The amdxdnaubufmap function allocates memory for sg and internal sg table structures, but it fails to free them if subsequent operations sgalloctablefrompages or dmamapsgtable fail...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: perf/core: The handling of buffer mapping fails correctly in perfmmap. After a buffer is successfully allocated or attached to an existing buffer, perfmmap attempts to map the buffer into the page table in read-only mode. If this...

CVE-2026-43445

In the Linux kernel, the following vulnerability has been resolved: e1000/e1000e: Fix leak in DMA error cleanup If an error is encountered while mapping TX buffers, the driver should unmap any buffers already mapped for that skb. Because count is incremented after a successful mapping, it will...

CVE-2026-43445

CVE-2026-43445 is a Linux kernel vulnerability in the e1000/e1000e drivers (and potentially igbvf) where a DMA mapping error cleanup leak could occur. The root cause was an off-by-one condition in the dma_error path: count was decremented before the loop, so if any TX buffer mappings succeeded be...
