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."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/amd/pds_core/dev.c"], "versions": [{"version": "45d76f492938cdc27ddadc16e1e75103f4cfbf56", "lessThan": "3231aff8ab26111c54e630b1a200fc43a729dd14", "status": "affected", "versionType": "git"}, {"version": "45d76f492938cdc27ddadc16e1e75103f4cfbf56", "lessThan": "10ae3180095bbe2d378c5b1d6f2f2fd74dda3cc2", "status": "affected", "versionType": "git"}, {"version": "45d76f492938cdc27ddadc16e1e75103f4cfbf56", "lessThan": "784dd2bdc622ed3cc6ef8e113aa1852e252de36f", "status": "affected", "versionType": "git"}, {"version": "45d76f492938cdc27ddadc16e1e75103f4cfbf56", "lessThan": "560d559324169fe0583d54c475b5329550a86f71", "status": "affected", "versionType": "git"}, {"version": "45d76f492938cdc27ddadc16e1e75103f4cfbf56", "lessThan": "0e46b6635b03d29807f810c3b415c4755a3f958d", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/amd/pds_core/dev.c"], "versions": [{"version": "6.4", "status": "affected"}, {"version": "0", "lessThan": "6.4", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.142", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.92", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.34", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.11", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.6.142"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.12.92"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.18.34"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "7.0.11"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/3231aff8ab26111c54e630b1a200fc43a729dd14"}, {"url": "https://git.kernel.org/stable/c/10ae3180095bbe2d378c5b1d6f2f2fd74dda3cc2"}, {"url": "https://git.kernel.org/stable/c/784dd2bdc622ed3cc6ef8e113aa1852e252de36f"}, {"url": "https://git.kernel.org/stable/c/560d559324169fe0583d54c475b5329550a86f71"}, {"url": "https://git.kernel.org/stable/c/0e46b6635b03d29807f810c3b415c4755a3f958d"}], "title": "pds_core: fix error handling in pdsc_devcmd_wait", "x_generator": {"engine": "bippy-1.2.0"}}}}
