{"id":"CVE-2026-64148","summary":"pds_core: fix error handling in pdsc_devcmd_wait","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npds_core: fix error handling in pdsc_devcmd_wait\n\nFix two cases where pdsc_devcmd_wait() returns stale success from\nthe completion register instead of an error:\n\n1. FW crash: If firmware stops running, the wait loop breaks early with\n   running=false. The condition \"if ((!done || timeout) && running)\" is\n   false, so error handling is bypassed and stale status is returned.\n   Check !running first and return -ENXIO.\n\n2. Timeout: If a command times out, err is set to -ETIMEDOUT but then\n   overwritten by pdsc_err_to_errno(status) which reads stale status.\n   Return -ETIMEDOUT immediately after cleaning up.\n\nBoth errors now propagate to pdsc_devcmd_locked() which queues\nhealth_work for recovery.","modified":"2026-07-22T03:32:04.132429802Z","published":"2026-07-19T15:40:38.816Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64148.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e46b6635b03d29807f810c3b415c4755a3f958d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/10ae3180095bbe2d378c5b1d6f2f2fd74dda3cc2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3231aff8ab26111c54e630b1a200fc43a729dd14"},{"type":"WEB","url":"https://git.kernel.org/stable/c/560d559324169fe0583d54c475b5329550a86f71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/784dd2bdc622ed3cc6ef8e113aa1852e252de36f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64148.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64148"},{"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":"45d76f492938cdc27ddadc16e1e75103f4cfbf56"},{"fixed":"3231aff8ab26111c54e630b1a200fc43a729dd14"},{"fixed":"10ae3180095bbe2d378c5b1d6f2f2fd74dda3cc2"},{"fixed":"784dd2bdc622ed3cc6ef8e113aa1852e252de36f"},{"fixed":"560d559324169fe0583d54c475b5329550a86f71"},{"fixed":"0e46b6635b03d29807f810c3b415c4755a3f958d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64148.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.4.0"},{"fixed":"6.6.142"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.92"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.34"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64148.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
