CVE-2026-93133

A flaw was found in the Linux kernel. In the riscvacpiaddprtdep function, the acpigethandle call can fail, leading to the linkhandle variable being uninitialized. This oversight could potentially lead to system instability or unexpected behavior...

CVE-2026-93132

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI implementation for RISC-V architectures. Specifically, the riscvacpiaddprtdep function contains a loop that incorrectly handles error conditions. This can cause the loop to skip necessary entry pointer updates,...

CVE-2026-93181

A flaw was found in the Linux kernel's uncore performance monitoring unit. An incorrect ordering of internal function calls during CPU online and offline operations can prevent the uncore box from being properly initialized or de-initialized. This mismanagement of resources could lead to system...

CVE-2026-93173

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF and Linux Security Module LSM subsystems. This vulnerability occurs when a sleepable LSM program is incorrectly handled during the freeing of non-sleepable BPF programs. An attacker could potentially trigger a system crash, leading...

CVE-2026-93172

A flaw was found in the Linux kernel's memory management mm/mminit. A missing allocation check for pgdat-percpunodestats can lead to a NULL dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial of Service DoS...

CVE-2026-93158

A flaw was found in the Linux kernel's crypto: sa2ul module. This vulnerability occurs because the saulprobe function does not properly handle errors when the system fails to create a necessary Direct Memory Access DMA pool for security context buffers. If the pool creation fails, the system...

CVE-2026-93146

A flaw was found in the Linux kernel's time namespace handling. The proctimenssetoffset function does not properly validate the nanosecond field tvnsec when setting time offsets. This oversight allows for invalid nanosecond values to be used in time calculations, which can lead to incorrect syste...

CVE-2026-93140

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. When an I/O error occurs during the writing of the Logical Volume Integrity Descriptor LVID buffer, the system incorrectly clears a flag indicating the buffer's validity. Subsequent operations, such as remounting the...

CVE-2026-93131

A flaw was found in the Linux kernel's dell-privacy driver. A race condition occurs when the priv-featurespresent data structure is accessed without holding the necessary list mutex. This allows the priv object to be freed prematurely, which could lead to system instability or a denial of service...

CVE-2026-93128

A flaw was found in the Linux kernel's lg-laptop driver. This issue occurs due to improper handling of LED Light Emitting Diode resources, where the system attempts to access an LED device that has not been properly registered or has already been unregistered. This improper resource management...

CVE-2026-93127

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. Incorrect handling of scalar identifiers during sign-extending and zero-extending stack operations can lead to a discrepancy between the BPF verifier's understanding of a register's value and its actual runtime value. Th...

CVE-2026-93124

A flaw was found in the Linux kernel's asus-wireless driver. When the driver is force-bound to a device lacking an ACPI Advanced Configuration and Power Interface companion object, it can lead to a NULL pointer dereference. This occurs because the asuswirelessprobe function incorrectly stores a...

CVE-2026-93121

A flaw was found in the Linux kernel's USB gadget function filesystem ffs component. Specifically, an issue in the ffsdmabuftransfer function's error handling can lead to undefined behavior. This occurs when a fence object is prematurely deallocated without proper initialization, potentially...

CVE-2026-93120

A flaw was found in the Linux kernel's USB gadget configfs component. This out-of-bounds read vulnerability occurs when the osdescqwsignshow function incorrectly handles string length during conversion. A local attacker could potentially exploit this to read sensitive information from memory,...

CVE-2026-93039

A flaw was found in the Linux kernel's ASoC Audio System on Chip meson driver. This vulnerability occurs in the mesoncardreallocatelinks function when memory reallocation krealloc fails after successfully moving data for the DAI link array. This can result in a use-after-free and double free...

CVE-2026-90417

A flaw was found in the Linux kernel's RDMA/cxgb4 component. When the device enters a fatal error state or experiences an allocation failure within the writetptentry function, it can lead to a memory leak and a double free vulnerability. A local attacker could potentially exploit this issue to...

CVE-2026-93038

A flaw was found in the Linux kernel's AD5686 digital-to-analog converter DAC driver. A local user can exploit this vulnerability by attempting to bind the driver to an unrecognized device name through the system file interface sysfs. This trigger leads to an invalid null pointer access due to...

CVE-2026-93183

A flaw was found in the Linux kernel's drm/lima component. The limavmcreate function is called prematurely, before virtual address VA start and end ranges are properly initialized. This can lead to the drmmminit function receiving invalid memory allocation ranges, which, if debug options are...

CVE-2026-93182

A flaw was found in the Linux kernel. A local user can trigger a divide-by-zero error in the scheduler's fair scheduling class sched/fair due to an unsigned 32-bit integer u32 overflow in the updatetgcfsrunnable function. This overflow corrupts internal scheduling data, leading to an invalid...
