"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: free madvise VMA array on L2 flush failure\n\nxe_vm_madvise_ioctl() allocates madvise_range.vmas in get_vmas().\nAfter get_vmas() succeeds with at least one VMA, error paths must go\nthrough free_vmas so the array is released before the madvise details are\ndestroyed.\n\nThe L2 flush validation path added for PAT madvise rejects some\nSVM/userptr ranges after get_vmas() has succeeded, but jumps directly to\nmadv_fini. This skips kfree(madvise_range.vmas), leaking the VMA array on\neach failed ioctl.\n\nJump to free_vmas instead, matching the other validation failure paths\nafter get_vmas() has succeeded.\n\n(cherry picked from commit c3a1c3579b1250060da73507a4acef712974c78a)"
