{"id":"CVE-2026-89577","summary":"dm-io: report non-retryable errors separatedly","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndm-io: report non-retryable errors separatedly\n\nThe error codes BLK_STS_NOTSUPP and BLK_STS_INVAL should not cause leg\nfailure on dm-raid1. This patch changes the interface to dm-io, so that\nit reports two error bitmaps - error_bits and unsup_bits. The unsup_bit\nbitmap tracks BLK_STS_NOTSUPP or BLK_STS_INVAL errors, the error_bits\nbitmap tracks all the other errors.\n\ndm-raid1 is changed so that it won't fail a leg if it receives an error\nin the unsup_bits bitmap.\n\nThis patch (with 62dc37a819a5) fixes misbehavior if the user uses\nunaligned bio vectors on dm-raid1.","modified":"2026-09-13T03:47:19.459285115Z","published":"2026-09-11T19:44:44.617Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89577.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/15fc1ec72e1f8089063d298550ada727e18f114a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/47a5e62f39875f371bded6e34ffb9cf15ccd813d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49694a363f7ecd5a52d1ea1a13c287ad6d196c35"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89577.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89577"},{"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":"5ff3f74e145adc79b49668adb8de276446acf6be"},{"fixed":"49694a363f7ecd5a52d1ea1a13c287ad6d196c35"},{"fixed":"15fc1ec72e1f8089063d298550ada727e18f114a"},{"fixed":"47a5e62f39875f371bded6e34ffb9cf15ccd813d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89577.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89577.json"}}],"schema_version":"1.9.0"}
