CVE-2026-64242

A flaw was found in the Linux kernel's USB gadget net2280 driver. This vulnerability occurs due to a double free error in the probe error path. When a gadget device is being initialized, an error can cause the device to be freed twice, leading to memory corruption. This can result in a denial of...

CVE-2026-64248

A flaw was found in the Linux kernel, specifically affecting systems using the MIPS architecture. During the shutdown process of a CPU, the kernel's internal mechanism responsible for managing concurrent data access Read-Copy Update or RCU is not properly informed that the CPU is no longer active...

CVE-2026-64211

A flaw was found in the Linux kernel. During certain CPU state transitions, the kernel's srcustruct mechanism may attempt to schedule tasks on processors that are not active or will never be online. This incorrect scheduling of workqueue handlers can lead to system unresponsiveness, specifically...

CVE-2026-64223

A flaw was found in the Linux kernel's mac80211 Wi-Fi driver. This vulnerability, an out-of-bounds read, occurs when parsing negotiated Time-To-Live Map TTLM elements. A remote attacker could craft a sparse map, causing the parser to read beyond the intended memory boundary. While direct policy...

CVE-2026-64215

A flaw was found in the Linux kernel's drm/msm/a6xx component. This vulnerability occurs because the a8xxhfisendperftable function does not properly check the return value of a memory allocation call kzalloc. An attacker could potentially exploit this missing check to trigger a NULL pointer...

CVE-2026-64209

A flaw was found in the Linux kernel, specifically within the Qualcomm QCOM QMP USBC PHY Physical Layer driver. An incorrect boundary check during the configuration of DisplayPort DP swing settings allows for an out-of-bounds array access. This vulnerability can lead to memory corruption,...

CVE-2026-64238

A flaw was found in the Linux kernel's gpio: shared component. A too wide critical section, intended to protect the offset field in the struct gpiosharedentry, can lead to a potential deadlock. This occurs during the removal of a shared General Purpose Input/Output GPIO proxy's parent. A successf...

CVE-2026-64255

A flaw was found in the Linux kernel's iwlwifi Intel Wireless WiFi driver. This vulnerability allows an attacker to cause an out-of-bounds memory access in the WiFi Block Acknowledgement BA session handlers. This occurs when the stamask value is zero, leading to an incorrect station ID calculatio...

CVE-2026-64228

A flaw was found in the Linux kernel's ethtool PHY Physical Layer driver. A local attacker can trigger a null pointer dereference by unbinding a PHY driver via sysfs while the device is still attached. This can lead to a kernel crash, resulting in a denial of service...

CVE-2026-64212

A flaw was found in the Linux kernel's iwlwifi driver. The iwlmldremovelink function does not properly check for a NULL pointer before dereferencing it. A local attacker could potentially exploit this null pointer dereference, leading to a system crash and a Denial of Service DoS...

Researcher Says AI Helped Develop Linux Traffic-Control Race Into Root Exploit

STAR Labs has published a Linux kernel exploit that turns an ordinary local user into root on the CentOS Stream 9 build it targeted. The flaw, tracked as CVE-2026-53264 CVSS score: 7.8, is a use-after-free race in the kernel's network traffic-control subsystem. Researcher Lee Jia Jie said...

kernel: net: bridge: use a stable FDB dst snapshot in RCU readers

A flaw was found in the Linux kernel. Inconsistent handling of local Forwarding Database FDB entries in the bridge networking component's RCU Read-Copy-Update readers can lead to a null-pointer dereference. A local attacker could exploit this by triggering a concurrent update to an FDB entry,...

kernel: tipc: fix double-free in tipc_buf_append()

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

USN-8620-1: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8620-1 linux-azure-5.15, linux-azure-fde-5.15, linux-oracle-5.15 vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8619-1 linux-hwe-6.8 vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...
