A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT Source Network Address Translation module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP Address Resolution...

CISA BOD 26-04 Timelines for Three Linux Kernel CVEs

Executive Summary CISA added three actively exploited Linux kernel vulnerabilities: CVE-2025-39682, CVE-2026-53266, and CVE-2025-39964 to its KEV Catalog on September 18, 2026, triggering a 3-day remediation deadline that passed on September 21. Under CISA BOD 26-04, a 3-day window applies to...

CVE-2026-93136

A flaw was found in the Linux kernel's Mobile Host Interface MHI endpoint driver. An issue in the error handling path during MHI device creation can lead to a resource leak. Specifically, if certain device setup operations fail, not all allocated device references are properly released. This can...

CVE-2026-93130

A flaw was found in the Linux kernel's dell-wmi-base module, which handles system management functions for Dell hardware. This vulnerability is a resource leak, meaning that system resources are not properly released after use. When the dell-wmi-base module fails to load, it does not correctly...

CVE-2026-93116

A flaw was found in the asus-wmi driver of the Linux kernel. During driver initialization, an error handling issue can lead to resource leaks. This occurs because cleanup calls for previously registered subsystems are bypassed when certain initialization functions fail. A local attacker could...

CVE-2026-93072

A flaw was found in the Linux kernel's irqchip/renesas-irqc driver. When the driver is removed, generic interrupt chips are not properly freed, leading to a resource leak. This can result in a use-after-free vulnerability, where a local attacker could potentially trigger a kernel crash...

CVE-2026-92524

A flaw was found in the Linux kernel's irqchip/gic-v3-its component. A resource leak occurs when the itsirqgicdomainalloc function fails to properly deallocate resources during error handling. This can lead to a denial of service DoS due to excessive memory consumption...

CVE-2026-92494

A flaw was found in the Linux kernel's ext4 filesystem. When handling orphan file blocks, the system may fail to properly release memory resources if block validation checks fail. This memory leak could lead to resource exhaustion over time, potentially resulting in a Denial of Service DoS for th...

CVE-2026-90119

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture ice1712 component. This vulnerability occurs when the sndice1712probe function, responsible for initializing the sound card, encounters an error. During such failures, the system does not properly release allocated ALSA...

CVE-2026-89944

A flaw was found in the Linux kernel's Audio System on Chip ASoC High Definition Audio Codec hdachda component. During the device probing process, a reference to an HDA link is acquired but not properly released if the ASoC component registration fails. This oversight leads to a reference count...

CVE-2026-89925

A flaw was found in KVM's guest debug handling within the Linux kernel. A local user, by repeatedly calling KVMSETGUESTDEBUG, can trigger a memory leak.
