CVE-2026-64330

A flaw was found in the Linux kernel's USB Type-C subsystem tcpm. A malicious USB-C partner device could exploit an out-of-bounds read vulnerability in the svdmconsumemodes function. By manipulating the SVID Standard or Vendor ID index, the partner device can force the system to register an...

CVE-2026-64343

A flaw was found in the Linux kernel. A race condition exists in the ldusb USB driver where a mutexunlock operation can attempt to access a mutex structure after it has been freed. This occurs when the release and disconnect functions race, leading to a use-after-free vulnerability. A local...

CVE-2026-64422

A flaw was found in the Linux kernel's IPv4 networking stack. Invalid values for net.ipv4.tcpreordering, particularly negative inputs, can lead to an integer overflow when processed. When tcpmtuprobing is enabled, this overflow can cause an out-of-bounds read within the tcpmtuprobe function. This...

CVE-2026-64374

A flaw was found in the Linux kernel's real-time RT scheduler. In non-real-time configurations, the RTPUSHIPI mechanism, designed to improve task migration, can lead to a live lock. This occurs when a CPU handling heavy network traffic is repeatedly interrupted by other CPUs attempting to schedul...

CVE-2026-64529

A flaw was found in the Linux kernel's QAT QuickAssist Technology driver. Unused character devices and IOCTLs Input/Output Control were exposed, which increased the potential attack surface. Removing these interfaces reduces the risk of future vulnerabilities and improves the overall security...

USN-8622-1 linux-nvidia, linux-nvidia-7.0 vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - Arm Firmware Framework for ARMv8-AFFA; CVE-2026-53354, CVE-2026-64520...

CVE-2026-64492

A flaw was found in the Linux kernel's tmp006 temperature sensor driver. This vulnerability occurs because the driver incorrectly handles the registration and de-registration of a hardware trigger. When the module is unloaded, a pointer to freed memory remains active, creating a 'dangling pointer...

Important: Red Hat Security Advisory: kernel security update

An update for kernel is now available for Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions and Red Hat Enterprise Linux 8.8 Telecommunications Update Service. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring Syst...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

CVE-2026-64505

A flaw was found in the Linux kernel's USB RNDIS gadget function. A missing length check for the RNDIS header in the rndisrmhdr function could allow an attacker to read data beyond the intended buffer. This out-of-bounds read vulnerability could lead to information disclosure or potentially a...

CVE-2026-64306

A flaw was found in the Linux kernel's Cryptographic API, specifically within the Counter Mode Deterministic Random Bit Generator CTRDRBG. The drbgctrgenerate function can incorrectly indicate a successful operation even when it has failed. This issue results in the output buffer remaining...

CVE-2026-64263
