  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/imagination: acquire vm_ctx-\u003Elock before mapping memory to GPU VM  The drm gpuvm code doesn\u0027t protect find operation against map operation, and the driver needs to ensure a map operation shouldn\u0027t happen when a find operation is in progress.  In some cases a find operation will be in progress when doing map/unmap operations, and the find operation will do a NULL pointer dereference.  An example of the stack trace of such NULL dereference is shown below:  \u0060\u0060\u0060 Unable to handle kernel access to user memory without uaccess routines at virtual address 0000000000000010  [\u003Cffffffff01e989d4\u003E] drm_gpuva_find\u002B0x28/0x6c [drm_gpuvm] [\u003Cffffffff01ed3a40\u003E] pvr_vm_unmap\u002B0x34/0x68 [powervr] [\u003Cffffffff01ec69da\u003E] pvr_ioctl_vm_unmap\u002B0x2e/0x50 [powervr] [\u003Cffffffff8080ce0a\u003E] drm_ioctl_kernel\u002B0x8e/0xdc [\u003Cffffffff8080d016\u003E] drm_ioctl\u002B0x1be/0x3e0 [\u003Cffffffff802bec3e\u003E] __riscv_sys_ioctl\u002B0xba/0xc4 [\u003Cffffffff80d858b2\u003E] do_trap_ecall_u\u002B0x23e/0x3f4 [\u003Cffffffff80d92288\u003E] handle_exception\u002B0x168/0x174 \u0060\u0060\u0060  As all occurences of drm_gpuva_find*() are already guarded by vm_ctx-\u003Elock, make pvr_vm_map() to acquire this lock to prevent disturbing any find operation. This fixes the NULL deference problem in drm_gpuva_find*().",
