A pool failure jumps to out_free_buffer_pools without\nh_free_logical_lan(), so PHYP still owns the buffer-list page when\nit is unmapped. request_irq() failure already issued the hypercall\nbefore taking the same label.\n\nMove that h_free to the shared post-register unwind so both paths\nderegister before the buffer list is unmapped.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/a065bd31ec462f6f9c267026b708dd020f122723","tags":[]},{"url":"https://git.kernel.org/stable/c/af0524bf4ce1a4cbd2946aa81751582951cfcab5","tags":[]},{"url":"https://git.kernel.org/stable/c/c54bbdf6f0731102a4bf7f5e4ee535b3ea415996","tags":[]},{"url":"https://git.kernel.org/stable/c/d24fdec1413c656d29298097926e77542785ca0c","tags":[]},{"url":"https://git.kernel.org/stable/c/decb4d4ead2c71ef698727734ab5024a872eb372","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
