As the free_irq only waits\nfor completion of hard interrupt handlers, the napi poll\nfunction could still be active. If cvm_oct_remove proceeds to\nfree the plat structure (which holds the NAPI instances), the\nactive poll function will access freed memory, resulting in a\nuse-after-free crash.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/158389d7af04bbf0664d91c2ce31fcc9eeace1eb","tags":[]},{"url":"https://git.kernel.org/stable/c/89f9f433271fad9351de6a3c713b45b2cfb23e4a","tags":[]},{"url":"https://git.kernel.org/stable/c/98f9036b2254c928cb44da0c77dba38f66f7d8f1","tags":[]},{"url":"https://git.kernel.org/stable/c/b2243ffaac14cc3639b5b32a371aac37f96ee554","tags":[]},{"url":"https://git.kernel.org/stable/c/b38fbd68cc36b4f478a1e3cfc169b8616ae1337d","tags":[]},{"url":"https://git.kernel.org/stable/c/c0a9a8586a63fda49e61a6b83360feac2a60d898","tags":[]},{"url":"https://git.kernel.org/stable/c/c124049c3a7006fd6caf629139a5722610bbffb4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
