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-2026-43445

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...

CVE-2026-43445 e1000/e1000e: Fix leak in DMA error cleanup

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...

Astra Linux – Vulnerability in Linux 5.10

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,...

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...

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 in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: perf/core: The handling of buffer mapping failures in perfmmap is incorrect. 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. I...

CVE-2025-47333

CVE-2025-47333 affects Qualcomm chipsets' cryptographic driver, with memory corruption occurring while handling buffer mapping operations. The root cause is a flaw in how the driver manages memory during mapBuffer processing, which may lead to crashes or unpredictable behavior. Exploitation detai...

PT-2026-1528

Name of the Vulnerable Software and Affected Versions versions prior to 2025 Description A memory corruption issue exists when handling buffer mapping operations within the cryptographic driver. The issue involves a flaw in how the driver manages memory, potentially leading to crashes or unexpect...

CVE-2022-50819 udmabuf: Set ubuf->sg = NULL if the creation of sg table fails

In the Linux kernel, the following vulnerability has been resolved: udmabuf: Set ubuf-sg = NULL if the creation of sg table fails When userspace tries to map the dmabuf and if for some reason e.g. OOM the creation of the sg table fails, ubuf-sg needs to be set to NULL. Otherwise, when the userspa...
