kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...
SUSE CVE-2026-43124
In the Linux kernel, the following vulnerability has been resolved: pstore: ramcore: fix incorrect success return when vmap fails In persistentramvmap, vmap may return NULL on failure. If offset is non-zero, adding offsetinpagestart causes the function to return a non-NULL pointer even though the...
UBUNTU-CVE-2026-43433
In the Linux kernel, the following vulnerability has been resolved: rustbinder: avoid reading the written value in offsets array When sending a transaction, its offsets array is first copied into the target proc's vma, and then the values are read back from there. This is normally fine because th...
CVE-2026-43462
CVE-2026-43462 affects the Linux kernel spacemit network driver. An error in the function emac_tx_mem_map() could leak DMA mappings on a mapping failure. This resource mismanagement may lead to a denial of service, impacting system availability. The published fix frees the leaked DMA mappings usi...
CVE-2026-43461 spi: amlogic: spifc-a4: Fix DMA mapping error handling
In the Linux kernel, the following vulnerability has been resolved: spi: amlogic: spifc-a4: Fix DMA mapping error handling Fix three bugs in amlsfcdmabuffersetup error paths: 1. Unnecessary goto: When the first DMA mapping sfc-daddr fails, nothing needs cleanup. Use direct return instead of goto...
CVE-2026-43434 rust_binder: check ownership before using vma
In the Linux kernel, the following vulnerability has been resolved: rustbinder: check ownership before using vma When installing missing pages or zapping them, Rust Binder will look up the vma in the mm by address, and then call vminsertpage or zappagerangesingle. However, if the vma is closed an...

Linux Distros Unpatched Vulnerability : CVE-2026-43348
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: mshvvtl: Fix vmemmapshift exceeding MAXFOLIOORDER When registering VTL0 memory via...
Linux Kernel Security Vulnerabilities
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the emactxmemmap function in the net spacemit component. When mapping errors occur, the DMA mappi...
CVE-2026-43178
A flaw was found in the Linux kernel's procfs component. A local user, by providing a malformed input buffer during a specific memory mapping query PROCMAPQUERY, can trigger an error in how the kernel manages process memory. This can lead to a double release of memory resources, potentially causi...

Integer overflow in `array::ReadWrite::new()` leading to potential memory corruption
In array::ReadWrite::new line 83 of accessor/src/array.rs, let bytes = mem::sizeof:: len can overflow usize when len is very large. In release mode, this silently wraps, potentially making bytes = 0. The mapper then maps with 0 bytes, and subsequent accesses e.g. readvolatileat lead to undefined...
CVE-2026-43008
A flaw was found in the Linux kernel's qixis-fpga driver. This vulnerability is due to incorrect error handling when initializing memory-mapped I/O Input/Output regions. An attacker could potentially exploit this flaw by triggering an error condition, which may lead to an invalid pointer...
