This bypasses hugepage_put_subpool()\nand can leave min_size reservations charged.\n\nUse hugepage_put_subpool() on the failure path, matching the normal\nput_super path.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/04f0354a4abf6793aa5b3f32e2b019ab206f344d","tags":[]},{"url":"https://git.kernel.org/stable/c/1d8be4ee81e73fcc52e58f47842d9a2277cfeaaa","tags":[]},{"url":"https://git.kernel.org/stable/c/308ab73e97c87bd0e142b11758faab7f88d82854","tags":[]},{"url":"https://git.kernel.org/stable/c/5b7fc7a1ce2a5f2cd8ed80a883157c7108074e0b","tags":[]},{"url":"https://git.kernel.org/stable/c/91c4f3a87862fd86594d5945512decbfa0b1d13d","tags":[]},{"url":"https://git.kernel.org/stable/c/dc2bd517ac0bce4ec7498644bd16b6db502df8e2","tags":[]},{"url":"https://git.kernel.org/stable/c/dfe848cadfde4179a0691da34f4bed36ff7185b5","tags":[]},{"url":"https://git.kernel.org/stable/c/f2d6cea221d777fab3ba18f805ba4c17c90e0b8b","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
