Title
misc: fastrpc: Don't remove map on creater_process and device_release
Summary
In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Don't remove map on creater_process and device_release Do not remove the map from the list on error path in fastrpc_init_create_process, instead call fastrpc_map_put, to avoid use-after-free. Do not remove it on fastrpc_device_release either, call fastrpc_map_put instead. The fastrpc_free_map is the only proper place to remove the map. This is called only after the reference count is 0.
Severity

No real root/init-namespace capability is required.\nUI:N - Exploitation needs only the attacker\u2019s own open/ioctl/close sequence; no victim action is required.\nS:U - Impact is kernel memory corruption and local privilege escalation within the same OS security authority, not a VM/IOMMU sandbox escape.\nC:H - Use-after-free of fastrpc_map objects enables heap reuse and arbitrary kernel read primitives per standard UAF exploitation.\nI:H - The same UAF enables heap spraying and arbitrary write/control-flow hijacking in the kernel.\nA:H - Use-after-free of list-linked map objects can cause kernel oops/panic even without full exploitation."
