CVE-2026-53158

A flaw was found in the Linux kernel's fastrpc component. This vulnerability occurs due to a NULL pointer dereference when the Digital Signal Processor DSP sends a glink message before the fastrpc driver is fully initialized. This can lead to system instability or a denial of service DoS conditio...

CVE-2026-53160

A flaw was found in the Linux kernel's fastrpc component. A race condition in the fastrpcmapcreate function allows for a use-after-free vulnerability. This could enable an attacker to cause system instability, disclose sensitive information, or potentially execute unauthorized code...

CVE-2026-53161

A flaw was found in the Linux kernel's fastrpc module. A race condition between closing a file descriptor and processing Digital Signal Processor DSP responses can lead to a use-after-free vulnerability. This allows a local attacker to potentially cause a system crash or, in some cases, execute...
