This can lead to a use-after-free of the socket object.\n\nWhen nfc_llcp_recv_cc() moves the socket from the connecting_sockets\nlist to the sockets list, it does so without holding the socket lock.\nIf llcp_sock_release() is executing concurrently, it might have already\nunlinked the socket and dropped its references, which can result in\nnfc_llcp_recv_cc() linking a freed socket into the live list.\n\nFix this by holding lock_sock() during the state transition and list\nmovement in nfc_llcp_recv_cc(). After acquiring the lock, check if\nthe socket is still hashed to ensure it hasn't already been unlinked\nand marked for destruction by the release path. This aligns the locking\npattern with recv_hdlc() and recv_disc()."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/nfc/llcp_core.c"], "versions": [{"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "dce85215a6c7b0fd753f577a4c487f647119884c", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "bd08bb7443c501d2f2a71d529e4afcf11c9b07d2", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "0b45c31746e1523d5d482fda8fcf54a35ac417f1", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "ee2d1a8a1833c5e56e9a1745e64b0b4edda732c2", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "ad8a27d63cac96bac441edd002209ebd996e12fb", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "650bdd8fdfab64a09ee474150313dbc48c374795", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "b2a60f7f846faaf5c2cdad4ea6d3a33e5f863183", "status": "affected", "versionType": "git"}, {"version": "a69f32af86e389dd232b1bb2269e202c1bfcc60f", "lessThan": "b493ea2765cc17cb8aa7e7544a4b6dcb05b6ed77", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/nfc/llcp_core.c"], "versions": [{"version": "3.6", "status": "affected"}, {"version": "0", "lessThan": "3.6", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.259", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.210", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.176", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.143", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.93", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.35", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.12", "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": "3.6", "versionEndExcluding": "5.10.259"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "5.15.210"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "6.1.176"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "6.6.143"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "6.12.93"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "6.18.35"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "7.0.12"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.6", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/dce85215a6c7b0fd753f577a4c487f647119884c"}, {"url": "https://git.kernel.org/stable/c/bd08bb7443c501d2f2a71d529e4afcf11c9b07d2"}, {"url": "https://git.kernel.org/stable/c/0b45c31746e1523d5d482fda8fcf54a35ac417f1"}, {"url": "https://git.kernel.org/stable/c/ee2d1a8a1833c5e56e9a1745e64b0b4edda732c2"}, {"url": "https://git.kernel.org/stable/c/ad8a27d63cac96bac441edd002209ebd996e12fb"}, {"url": "https://git.kernel.org/stable/c/650bdd8fdfab64a09ee474150313dbc48c374795"}, {"url": "https://git.kernel.org/stable/c/b2a60f7f846faaf5c2cdad4ea6d3a33e5f863183"}, {"url": "https://git.kernel.org/stable/c/b493ea2765cc17cb8aa7e7544a4b6dcb05b6ed77"}], "title": "nfc: llcp: Fix use-after-free race in nfc_llcp_recv_cc()", "x_generator": {"engine": "bippy-1.2.0"}}}}
