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...
