In the Linux kernel, the following vulnerability has been resolved: drivers/base/memory: set mem-altmap after successful device registration If addmemoryblock fails at xastore under memory pressure for example, deviceunregister is called, which eventually triggers memoryblockrelease with mem-altm...

CVE-2026-64244 drivers/base/memory: set mem->altmap after successful device registration

In the Linux kernel, the following vulnerability has been resolved: drivers/base/memory: set mem-altmap after successful device registration If addmemoryblock fails at xastore under memory pressure for example, deviceunregister is called, which eventually triggers memoryblockrelease with mem-altm...

CVE-2026-64244

In the Linux kernel's drivers/base/memory , mem->altmap is assigned before __add_memory_block() completes. If xa_store() fails (e.g., under memory pressure), device_unregister() triggers memory_block_release() with altmap still set, causing a WARN_ON. The fix delays altmap assignment until aft...

CVE-2026-64241 gpio: rockchip: teardown bugs and resource leaks

In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: teardown bugs and resource leaks Address several teardown issues and resource leaks in the driver's remove path and error handling: 1. Debounce clock reference leak: The debounce clock bank-dbclk is obtained using...

CVE-2026-64236 i2c: davinci: fix division by zero on missing clock-frequency

In the Linux kernel, the following vulnerability has been resolved: i2c: davinci: fix division by zero on missing clock-frequency When the 'clock-frequency' property is missing from the device tree, the driver falls back to DAVINCII2CDEFAULTBUSFREQ. However, this macro was defined in kHz 100,...

CVE-2026-64236

In the Linux kernel, the following vulnerability has been resolved: i2c: davinci: fix division by zero on missing clock-frequency When the 'clock-frequency' property is missing from the device tree, the driver falls back to DAVINCII2CDEFAULTBUSFREQ. However, this macro was defined in kHz 100,...

CVE-2026-64234

In the Linux kernel, the following vulnerability has been resolved: tty: serial: pchuart: add check for dmaalloccoherent Add a check for dmaalloccoherent failure to prevent a potential NULL pointer dereference in dmahandlerx. Properly release DMA channels and the PCI device reference using a goto...

CVE-2026-64234

The CVE-2026-64234 entry concerns the Linux kernel tty/serial driver pch_uart. The root cause is a missing check of the return value from dma_alloc_coherent(), which could yield a NULL pointer, triggering a crash in dma_handle_rx(). The fix adds a guard for dma_alloc_coherent() failure and ensure...

EUVD-2026-48638

In the Linux kernel, the following vulnerability has been resolved: regulator: tps65219: fix irqdata.rdev not being assigned Commit 64a6b577490c "regulator: tps65219: Remove debugging helper function" removed the tps65219getrdevbyname helper along with the irqdata.rdev assignment that depended on...

CVE-2026-64230

CVE-2026-64230 affects the Linux kernel regulator driver for the TPS65219 family. The root cause was the removal of the tps65219_get_rdev_by_name() helper, which led to irq_data.rdev being uninitialized for IRQs. This caused undefined behavior when regulator_notifier_call_chain() ran from the IRQ...

CVE-2026-64227

Summary: CVE-2026-64227 in the Linux kernel fixes a NULL-deref/invalid match during ACPI companion probing. Root cause (as described): Platform drivers could be forced to match a device not in their ID list via device_match_driver_override(), so drivers handling core ACPI devices must verify the ...
