CVE-2026-45891

A flaw was found in the Linux kernel's hns3 network driver. This double-free vulnerability occurs due to incorrect handling of the txspare buffer during ring parameter setup. If memory allocation fails in the error cleanup path, a stale pointer to backup memory is erroneously freed twice. This ca...

CVE-2025-68746 spi: tegra210-quad: Fix timeout handling

In the Linux kernel, the following vulnerability has been resolved: spi: tegra210-quad: Fix timeout handling When the CPU that the QSPI interrupt handler runs on typically CPU 0 is excessively busy, it can lead to rare cases of the IRQ thread not running before the transfer timeout is reached...

Linux kernel 安全漏洞

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 improper timeout handling, which could cause the currxfer field to point to stale memory...

CVE-2025-68746: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: spi: tegra210-quad: Fix timeout handling When the CPU that the QSPI interrupt handler runs on typically CPU 0 is excessively busy, it can lead to rare cases of the IRQ thread not running before the transfer timeout is reached...

AMD CPU 安全漏洞

AMD CPUs are a family of CPUs from AMD. An unspecified vulnerability exists in AMD CPUs, which can be exploited by an attacker to run SEV-SNP clients with stale TLB entries, resulting in a loss of data integrity...

CVE-2025-38554

CVE-2025-38554 in the Linux kernel describes a use-after-free (UAF) involving VMAs: if vma->mm is freed after vma->vm_refcnt has dropped, a recycled VMA could be mishandled, leading to UAF. The race can occur when VMAs are recycled under RCU (with SLAB_TYPESAFE_BY_RCU) and lock_vma_under_rc...

CVE-2025-22013 KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state There are several problems with the way hyp code lazily saves the host's FPSIMD/SVE state, including: Host SVE being discarded unexpectedly due to inconsistent...

kernel: NFSD: Finish converting the NFSv2 GETACL result encoder

A flaw was identified in the Linux kernel’s NFSD NFSv2 GETACL result encoder. During conversion to xdrstream, leftover code erroneously set the pagelen field of the send buffer. The XDR stream encoders are expected to manage buffer length automatically, and the incorrect manual setting can result...
