kernel: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item

A resource exhaustion vulnerability was found in the Kernel Same-page Merging KSM subsystem of the Linux kernel. When scanning processes with large sparse virtual memory mappings e.g., 32 TiB with one mapped page, ksmd inefficiently walks every address rather than skipping unmapped holes. This...

CVE-2026-64413

A flaw was found in the Linux kernel's netfilter ebtables component. This vulnerability involves an uninitialized pointer free that can occur when the system's CPU mask is sparse and a memory allocation fails. Under these specific and unlikely conditions, the kernel might attempt to free an...

TencentOS Server 4: skopeo (TSSA-2026:0747)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0747 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

CVE-2026-64413

CVE-2026-64413 relates to the Linux kernel netfilter/ebtables path, specifically the zero chainstack array issue. The advisory describes that if cpu_possible_mask is sparse (e.g., CPU 0 and CPU 2 possible, CPU 1 not), the allocation loop can skip an entry and, if vmalloc_node() fails later, the c...

CVE-2026-64349

CVE-2026-64349 affects the DesignWare USB3 (dwc3) driver in the Linux kernel . In dwc3_ulpi_setup() (drivers/usb/dwc3/core.c), the functions dwc3_readl() and dwc3_writel() are incorrectly passed dwc3->regs (a void __iomem *) instead of the expected struct dwc3 * pointer. This type mismatch acr...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the dwc3 ulpi setup function where it incorrectly passes dwc3-regs to the dwc3 readl and dwc3 writel functions. These functions are designed to take the dwc3 structure...

CVE-2026-16280

An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in...
