But if there is no next packet and the interface is\nbrought down instead, ice_clean_tx_ring() -> ice_unmap_and_free_tx_buf()\nwill find the tx_buf and free the skb for the second time.\n\nThe fix is to reset the tx_buf type to ICE_TX_BUF_EMPTY in the error\npath, so that ice_unmap_and_free_tx_buf().\nMove the initialization of 'first' up, to ensure it's already valid in\ncase we hit the linearization error path.\n\nThe bug was spotted by AI while I had it looking for something else.\nIt also proposed an initial version of the patch.\n\nI reproduced the bug and tested the fix by adding code to inject\nfailures, on a build with KASAN.\n\nI looked for similar bugs in related Intel drivers and did not find any."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/intel/ice/ice_txrx.c"], "versions": [{"version": "d76a60ba7afb89523c88cf2ed3a044ce4180289e", "lessThan": "4c08fc2119ef0281cfa2cee007acf0a251be55f2", "status": "affected", "versionType": "git"}, {"version": "d76a60ba7afb89523c88cf2ed3a044ce4180289e", "lessThan": "1a303baa715e6b78d6a406aaf335f87ff35acfcd", "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/intel/ice/ice_txrx.c"], "versions": [{"version": "4.17", "status": "affected"}, {"version": "0", "lessThan": "4.17", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.10", "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": "4.17", "versionEndExcluding": "7.0.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.17", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/4c08fc2119ef0281cfa2cee007acf0a251be55f2"}, {"url": "https://git.kernel.org/stable/c/1a303baa715e6b78d6a406aaf335f87ff35acfcd"}], "title": "ice: fix double-free of tx_buf skb", "x_generator": {"engine": "bippy-1.2.0"}}}}
