{"id":"CVE-2026-72082","summary":"scsi: elx: efct: Fix refcount leak in efct_hw_io_abort()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: elx: efct: Fix refcount leak in efct_hw_io_abort()\n\nWhen efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path\nreturns -ENOSPC without releasing the reference obtained via\nkref_get_unless_zero() earlier in the function. All other error paths\ncorrectly drop the reference. This causes a permanent reference leak on the\nio_to_abort object.\n\nAdditionally, the abort_in_progress flag is left set to true on this path,\nwhich means future abort attempts for the same I/O will immediately return\n-EINPROGRESS even though the abort was never submitted, effectively\nblocking recovery.\n\nFix this by adding the missing kref_put() call and reset abort_in_progress\nto false, matching the cleanup done in the efct_hw_wq_write() failure path\nbelow.","modified":"2026-08-18T03:31:21.744338Z","published":"2026-08-15T05:52:31.291Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72082.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1c6e186c722cfa9a58ebe841f91ab2ddf8570cc7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c007acf7b31c39c08ce4959451ad00b19be4c1f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/62cf39a9770a6f29df59fd0edb0a05234a8b07f2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/747eaead2db298abfda2aa505f6d03775b40fe5f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b871369cbb4532f6715e044d6b9c4ceb036e5b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cf97ea7b164a1881c7219f5222219c9d0fac4204"},{"type":"WEB","url":"https://git.kernel.org/stable/c/faa59add4808fbf92e7d15bfd8770d2682c2b953"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72082.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72082"},{"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":"63de51327a64c74e85611a0161eaae71256a3b6d"},{"fixed":"cf97ea7b164a1881c7219f5222219c9d0fac4204"},{"fixed":"1c6e186c722cfa9a58ebe841f91ab2ddf8570cc7"},{"fixed":"62cf39a9770a6f29df59fd0edb0a05234a8b07f2"},{"fixed":"faa59add4808fbf92e7d15bfd8770d2682c2b953"},{"fixed":"9b871369cbb4532f6715e044d6b9c4ceb036e5b6"},{"fixed":"747eaead2db298abfda2aa505f6d03775b40fe5f"},{"fixed":"2c007acf7b31c39c08ce4959451ad00b19be4c1f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72082.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72082.json"}}],"schema_version":"1.9.0"}
