CVE-2025-38188

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm/a7xx: Call CP_RESET_CONTEXT_STATE<br /> <br /> Calling this packet is necessary when we switch contexts because there<br /> are various pieces of state used by userspace to synchronize between BR<br /> and BV that are persistent across submits and we need to make sure that<br /> they are in a "safe" state when switching contexts. Otherwise a<br /> userspace submission in one context could cause another context to<br /> function incorrectly and hang, effectively a denial of service (although<br /> without leaking data). This was missed during initial a7xx bringup.<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/654924/
