CVE-2026-46282

A flaw was found in the Linux kernel's iio: frequency: admv1013 driver. This vulnerability occurs when the system attempts to read a device property, and an uninitialized string is used, leading to a NULL pointer dereference. This could allow a local attacker to trigger a system crash, resulting ...

CVE-2026-46292

A flaw was found in the Linux kernel's generic power domain genpd component. When a virtual device is detached from a power management PM domain, the pmruntimedisable function is not called, leaving runtime PM enabled for the detached device. This oversight can lead to critical errors, including ...

CVE-2026-46296

A flaw was found in the Linux kernel's s3c64xx Serial Peripheral Interface SPI driver. An issue with incorrect DMA Direct Memory Access channel deallocation during driver unbind could lead to a NULL-pointer dereference. This vulnerability can cause a system crash, resulting in a denial of service...

CVE-2026-46297

A flaw was found in the Linux kernel's libwx network driver. Incorrect handling of virtual function VF miscellaneous interrupts, specifically using requestthreadedirq with a null threaded handler and the IRQFONESHOT flag, can trigger a kernel warning. This issue may lead to system instability or...

CVE-2026-46305

A flaw was found in the Linux kernel, specifically within the rtl8723bs staging driver's osdep module.
