CVE-2025-38076

CVE-2025-38076 concerns the Linux kernel vulnerability related to module unloading and allocation tags. The issue arises from a use-after-free risk when memory containing a module’s allocation tags remains alive after unloading, because percpu counters referenced by those tags could be freed by f...

CVE-2025-38071

In the Linux kernel, the following vulnerability has been resolved: x86/mm: Check return value from memblockphysallocrange At least with CONFIGPHYSICALSTART=0x100000, if there is 4 MiB of contiguous free memory available at this point, the kernel will crash and burn because memblockphysallocrange...

CVE-2025-38071

CVE-2025-38071 affects the Linux kernel (x86/mm). Root cause: memblock_phys_alloc_range() may return 0 on failure when CONFIG_PHYSICAL_START=0x100000, causing memblock_phys_free() to mis-handle the first 4 MiB of memory and crash. The vulnerability is resolved in the kernel by checking the return...

CVE-2025-38043

CVE-2025-38043 affects the Linux kernel firmware/arm_ffa path: a fix sets the dma_mask for FFA devices to prevent DMA allocation using a raw device pointer, which previously triggered a kernel warning “dma_alloc_attrs” in mapping.c. The vulnerability’s impact, per the description, is to avoid mis...
