{"id":"CVE-2022-49429","summary":"RDMA/hfi1: Prevent panic when SDMA is disabled","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/hfi1: Prevent panic when SDMA is disabled\n\nIf the hfi1 module is loaded with HFI1_CAP_SDMA off, a call to\nhfi1_write_iter() will dereference a NULL pointer and panic. A typical\nstack frame is:\n\n  sdma_select_user_engine [hfi1]\n  hfi1_user_sdma_process_request [hfi1]\n  hfi1_write_iter [hfi1]\n  do_iter_readv_writev\n  do_iter_write\n  vfs_writev\n  do_writev\n  do_syscall_64\n\nThe fix is to test for SDMA in hfi1_write_iter() and fail the I/O with\nEINVAL.","modified":"2026-04-02T08:27:35.735135Z","published":"2025-02-26T02:12:48.646Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1293-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49429.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e4dda8b3f4c07ee9ea670a10ea3171a5e63a86f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/22e7e400fd1a890db2ea13686324aff50e972f4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/29952ab85d6c3fe0b7909d9a737f10c58bf6824d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/32e6aea33944f364d51cd263e4cd236393a188b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/33794e8e9bcb4affc0ebff9cdec85acc8b8a1762"},{"type":"WEB","url":"https://git.kernel.org/stable/c/629e052d0c98e46dde9f0824f0aa437f678d9b8f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc80d3c37cec9d6ddb140483647901bc7cc6c31d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e60ad83f645ee6fadd5a8057ba267aeec54f08fe"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49429.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49429"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0cb2aa690c7ef14ad1f544288349abb5434bb75d"},{"fixed":"33794e8e9bcb4affc0ebff9cdec85acc8b8a1762"},{"fixed":"0e4dda8b3f4c07ee9ea670a10ea3171a5e63a86f"},{"fixed":"e60ad83f645ee6fadd5a8057ba267aeec54f08fe"},{"fixed":"cc80d3c37cec9d6ddb140483647901bc7cc6c31d"},{"fixed":"32e6aea33944f364d51cd263e4cd236393a188b6"},{"fixed":"29952ab85d6c3fe0b7909d9a737f10c58bf6824d"},{"fixed":"22e7e400fd1a890db2ea13686324aff50e972f4f"},{"fixed":"629e052d0c98e46dde9f0824f0aa437f678d9b8f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49429.json"}}],"schema_version":"1.7.5"}
