kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle

A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...

CVE-2026-64497

A flaw was found in the Linux kernel's iio: chemical: scd30 driver, which manages a specific type of sensor. This vulnerability involves an error in how the driver processes numerical data, specifically a 'sign-extension bug' that can corrupt a part of a floating-point number called the exponent...

CVE-2026-64317

A flaw was found in the Linux kernel's ISO 9660 file system isofs component. A remote attacker could exploit this vulnerability by providing a specially crafted ISO 9660 image containing a malformed Rock Ridge symbolic link record. This flaw allows for an out-of-bounds read, leading to the...

CVE-2026-64336

A flaw was found in the Linux kernel's keyspanpda USB serial driver. An issue with the write callback function allows it to report more data written than was actually provided. This can lead to the system writing data beyond its allocated buffer, resulting in an information leak. A local attacker...

CVE-2026-64484

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture es1938 sound driver. This vulnerability arises when a memory allocation failure causes the sndctlnew1 function to return a null value. The sndes1938mixer function then attempts to use this null value without proper...

CVE-2026-64458

A flaw was found in the Linux kernel's Data Access MONitor DAMON subsystem. A local user with write permissions to the system file system sysfs can exploit this vulnerability by configuring extreme zero or excessively high monitoring intervals. This improper handling of interval values can lead t...

CVE-2026-64308

A flaw was found in the Linux kernel's crypto: ccp module, which handles AMD Secure Encrypted Virtualization SEV and Secure Nested Paging SNP features. A local user, by sending specific commands through the /dev/sev interface, could exploit improper initialization handling. If SEV initialization...

RLSA-2026:47017 Important: kernel security, bug fix, and enhancement update

CVE-2026-64559

In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in PKEYVERIFYPROTK ioctl Explicitly check the buffer length request structure provided by user-space and fail, if it exceeds the buffer size...

CVE-2026-64560

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Prevent UAF caused by non-leader exec race Wongi and Jungwoo decoded and reported a non-leader exec related race which can result in an UAF: systimerdelete exec posixcputimerdel // Observes old leader p =...

CVE-2026-64558

In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in pkeypckmo handler implementation Explicitly check the length of the target buffer in the pkeypckmo implementation of the keytoprotkey handler function. The handler function fails, if the generated outpu...

CVE-2026-64274

A flaw was found in the Linux kernel's Goodix touchscreen driver. An attacker with physical access to the I2C bus, or a malicious touchscreen controller, could exploit a vulnerability where the driver fails to properly validate the number of reported touch points. This could lead to a stack...

CVE-2026-64480

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA ice1712 driver. This vulnerability occurs because the sndctlnew1 function, which allocates memory, can return a null value upon failure, but the driver does not properly check for this. An attacker could potentially...

CVE-2026-64315

A flaw was found in the Linux kernel's Cryptographic Acceleration and Assurance Module CAAM driver. This vulnerability allows for the leakage of sensitive cryptographic key material. When the kernel's dynamic debugging feature is enabled, an attacker could potentially exploit improper handling of...

CVE-2026-64282

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for arm64 architectures. A race condition between the kvmtranslatevncr function and an MMU Memory Management Unit notifier can lead to a Page Frame Number PFN leak. This occurs because an early return in kvmtranslatevncr fail...

CVE-2026-64341

A flaw was found in the Linux kernel's USB iowarrior driver. This vulnerability involves a use-after-free error, which occurs when the system attempts to use memory that has already been deallocated. This specific issue arises from a race condition during device disconnection, where the mutexunlo...

CVE-2026-64312

A flaw was found in the Linux kernel's parallel cryptography pcrypt subsystem. When the system falls back to a non-parallel processing path, it fails to properly restore the original callback function and data. This oversight can lead to an asynchronous completion running an incorrect callback,...

CVE-2026-64284

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 systems. This vulnerability occurs when KVM handles fastpath exits, where it may fail to execute vendor-specific cleanup operations before returning control to the virtual machine's userspace. Consequently, memory...
