Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from a BAM transaction redistribution that could lead to a mapping failure...

UBUNTU-CVE-2025-38066

In the Linux kernel, the following vulnerability has been resolved: dm cache: prevent BUGON by blocking retries on failed device resumes A cache device failing to resume due to mapping errors should not be retried, as the failure leaves a partially initialized policy object. Repeating the resume...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: eth:bnxt: fixed the issue of missing ring index trimming on the error path. The commit under “Fixes” changed txprod to be a free-running entity, but this was overlooked; the issue was only masked on the Tx error path. This causes...

CVE-2025-37873 eth: bnxt: fix missing ring index trim on error path

In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: fix missing ring index trim on error path Commit under Fixes converted txprod to be free running but missed masking it on the Tx error path. This crashes on error conditions, for example when DMA mapping fails...

CVE-2025-37873

The CVE-2025-37873 entry concerns the Linux kernel Ethernet driver for Broadcom/BNXT (eth: bnxt). The issue arises in the Tx path after a conversion to a free-running tx_prod, where masking on the Tx error path was missed, causing a crash on error conditions such as DMA mapping failures. The root...

kernel: io_uring: Fix release of pinned pages when __io_uaddr_map fails

A flaw was found in the iouring subsystem in the Linux kernel, where pinned pages are not properly released if the iouaddrmap function fails. This could lead to resource leaks or other unintended behaviors...

DEBIAN-CVE-2024-50170

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix potential memory leak in bcmaspxmit The bcmaspxmit returns NETDEVTXOK without freeing skb in case of mapping fails, add devkfreeskb to fix it...

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix potential memory leak in bcmaspxmit The bcmaspxmit returns NETDEVTXOK without freeing skb in case of mapping fails, add devkfreeskb to fix it...

UBUNTU-CVE-2022-49026

In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100xmitprepare In e100xmitprepare, if we can't map the skb, then return -ENOMEM, so e100xmitframe will return NETDEVTXBUSY and the upper layer will resend the skb. But the skb is already free...

AZL-51986 CVE-2024-50001 affecting package kernel for versions less than 5.15.173.1-1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix error path in multi-packet WQE transmit Remove the erroneous unmap in case no DMA mapping was established The multi-packet WQE transmit code attempts to obtain a DMA mapping for the skb. This could fail, e.g. under...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from incorrect handling in the e100xmitprepare function, which could cause a skb to be incorrectly released on a...

SUSE CVE-2021-47047

In the Linux kernel, the following vulnerability has been resolved: spi: spi-zynqmp-gqspi: return -ENOMEM if dmamapsingle fails The spi controller supports 44-bit address space on AXI in DMA mode, so set dmaaddrt width to 44-bit to avoid using a swiotlb mapping. In addition, if dmamapsingle fails...

SUSE CVE-2004-1071

The binfmtelf loader binfmtelf.c in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, does not properly handle a failed call to the mmap function, which causes an incorrect mapped image and may allow local users to execute arbitrary code...

SUSE CVE-2014-3601

The kvmiommumappages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to 1 cause a denial of service host OS memory corruption or possibly have unspecified other impact by...
