In the Linux kernel, the following vulnerability has been resolved: spi: amlogic-spisg: Fix memory leak in amlspisgprobe In amlspisgprobe, ctlr is allocated by spialloctarget/spiallochost, but fails to call spicontrollerput in several error paths. This leads to a memory leak whenever the driver...

CVE-2026-31391

A flaw was found in the Linux kernel's atmel-sha204a component. This issue arises when the system attempts to allocate memory, and that allocation fails. If not properly handled, a resource counter, tfmcount, is not correctly decremented, leading to a resource leak. This can be exploited by a loc...

CVE-2026-23475

CVE-2026-23475 affects the Linux kernel SPI subsystem. The issue was a NULL pointer dereference window in per‑CPU controller statistics: stats were allocated only after controller registration with driver core, so early sysfs access could dereference NULL. The fix moves statistics allocation to t...
