CVE-2026-53160

In CVE-2026-53160, the Linux kernel misc: fastrpc subsystem had a use-after-free race in fastrpc_map_create. Specifically, fastrpc_map_lookup returned a raw pointer after releasing fl->lock, and the caller then invoked fastrpc_map_get (kref_get_unless_zero) on that unprotected pointer. A concu...

CVE-2026-53159

The CVE-2026-53159 entry describes a Linux kernel vulnerability in the fastrpc path where fastrpc_get_args() uses find_vma() to locate the VMA for a user pointer and compute a DMA address offset. If the address lies in a gap before the returned VMA, (ptr & PAGE_MASK) - vma->vm_start underflows...

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix DMA address corruption due to findvma misuse fastrpcgetargs uses findvma to look up the VMA for a user-provided pointer and compute a DMA address offset. When the address falls in a gap before the returned VMA,...

EUVD-2026-39249

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Fix NULL pointer dereference in rpmsg callback A NULL pointer dereference was observed on Hawi at boot when the DSP sends a glink message before fastrpcrpmsgprobe has completed initialization: Unable to handle kern...

CVE-2026-53158

The CVE-2026-53158 issue affects the Linux kernel’s fastrpc rpmsg path. A NULL pointer dereference could occur at boot when a DSP glink message arrives before fastrpc_rpmsg_probe() has finished initialization, causing a crash from an uninitialized spinlock on the fastrpc_channel_ctx. The root cau...
