overflow is reached while parsing NCI RF_DISCOVER_NTF frames delivered by the NFC controller from an NFC peer/tag in RF range (nci_recv_frame → nci_rx_work → nci_ntf_packet → nci_rf_discover_ntf_packet → nci_add_new_protocol), matching established AV:A scoring for NCI bugs (CVE-2024-35915, CVE-2024-38381, CVE-2023-52502).\nAC:L - A single crafted Discover NTF (e.g. NFC-F with rf_tech_specific_params_len=0 leaving sensf_res_len uninitialized, or any path that supplies a length > array size) deterministically drives the unbounded memcpy; ~93% of random u8 lengths exceed the 18-byte field, with no race or attacker-uncontrollable precondition.\nPR:N - NFC discovery notifications are processed with no authentication from an adjacent peer while the platform NFC stack is polling, and the same parser is reachable via N_NCI without credentials; no attacker-held capability is required on the severe path.\nUI:N - Frames are handled asynchronously on nci_rx_work during normal autonomous NFC poll/discovery; no victim action such as mounting a filesystem or confirming a prompt is required.\nS:U - The out-of-bounds write corrupts kernel heap state inside struct nci_dev (targets[] and adjacent fields) within the host OS security authority, with no VM escape, IOMMU bypass, or sandbox boundary cross.\nC:H - The oversized memcpy both reads past the 18-byte source on the stack and writes past target->sensf_res into adjacent nfc_target/nci_dev heap memory, and the inflated sensf_res_len is later exported via nfc_genl_send_target netlink attributes—memory corruption with a disclosure path, scored Confidentiality High.\nI:H - This is a genuine heap out-of-bounds write of up to 255 bytes into ndev->targets[] (and past the array for late indices into n_targets and following nci_dev fields), enabling corruption of kernel NFC state and control-flow primitives per OOB-write guidance.\nA:H - Syzkaller already hit a fortify WARNING that panics under panic_on_warn, and an unbounded heap write in workqueue context reliably produces kernel oops/panic even when not fully exploited."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/nfc/nci/ntf.c"],"versions":[{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"6b37f0dc0638d13a006f2f24d2f6ca61e83bc714","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"dbdcfb9f6748218a149f62468d6297ce3f014e9c","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"cff35329070b96b4484d23f9f48a5ca2c947e750","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"6778434706940b8fad7ef35f410d2b9929f256d2","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"27eb2d7a1b9987b6d0429b7716b1ff3b82c4ffc9","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"908b2da426fe9c3ce74cf541ba40e7a4251db191","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"f41547546db9af99da2c34e3368664d7a79cefae","status":"affected","versionType":"git"},{"version":"019c4fbaa790e2b3f11dab0c8b7d9896d77db3e5","lessThan":"e329e71013c9b5a4535b099208493c7826ee4a64","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/nci/ntf.c"],"versions":[{"version":"3.4","status":"affected"},{"version":"0","lessThan":"3.4","status":"unaffected","versionType":"semver"},{"version":"4.9.336","lessThanOrEqual":"4.9.*","status":"unaffected","versionType":"semver"},{"version":"4.14.302","lessThanOrEqual":"4.14.*","status":"unaffected","versionType":"semver"},{"version":"4.19.269","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.227","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.159","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.83","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.0.13","lessThanOrEqual":"6.0.*","status":"unaffected","versionType":"semver"},{"version":"6.1","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":"3.4","versionEndExcluding":"4.9.336"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"4.14.302"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"4.19.269"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"5.4.227"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"5.10.159"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"5.15.83"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"6.0.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"6.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6b37f0dc0638d13a006f2f24d2f6ca61e83bc714"},{"url":"https://git.kernel.org/stable/c/dbdcfb9f6748218a149f62468d6297ce3f014e9c"},{"url":"https://git.kernel.org/stable/c/cff35329070b96b4484d23f9f48a5ca2c947e750"},{"url":"https://git.kernel.org/stable/c/6778434706940b8fad7ef35f410d2b9929f256d2"},{"url":"https://git.kernel.org/stable/c/27eb2d7a1b9987b6d0429b7716b1ff3b82c4ffc9"},{"url":"https://git.kernel.org/stable/c/908b2da426fe9c3ce74cf541ba40e7a4251db191"},{"url":"https://git.kernel.org/stable/c/f41547546db9af99da2c34e3368664d7a79cefae"},{"url":"https://git.kernel.org/stable/c/e329e71013c9b5a4535b099208493c7826ee4a64"}],"title":"NFC:
