The flaw is reached only through a local write to /proc/self/attr/current or /proc/self/attr/exec (changeprofile/exec), which flows through proc_pid_attr_write and the AppArmor setprocattr hook into aa_change_profile(); there is no network, adjacent-radio, or physical-device entry point.\nAC:L - Once a confined task with policy-granted changeprofile and PR_SET_NO_NEW_PRIVS calls the interface, fn_label_build_in_scope() failure (e.g., GFP_KERNEL ENOMEM from memory pressure) is reliably attacker-influenced and immediately triggers the invalid dereference without races or victim-dependent timing.\nPR:L - Exploitation requires a local unprivileged process confined by AppArmor whose policy permits changeprofile/onexec to the requested target; prctl(PR_SET_NO_NEW_PRIVS) is self-settable and does not require real root or init-namespace capabilities.\nUI:N - The attacker triggers the bug by writing to their own process attribute file; no separate victim action such as opening a file, mounting a filesystem, or clicking a link is required.\nS:U - The vulnerable AppArmor kernel code and the resulting kernel oops/panic affect the same OS security authority; this is not a VM escape, IOMMU bypass, or cross-authority sandbox breakout as defined by CVSS scope.\nC:H - aa_label_is_unconfined_subset() dereferences the failed label pointer (NULL or ERR_PTR) to read aa_label fields such as size/vec; ERR_PTR values are non-NULL kernel-range addresses, so the fault path includes an invalid kernel-memory read that can leak data before oops under worst-case layout.\nI:N - The bug performs invalid reads through a bad label pointer and does not write memory, corrupt adjacent objects, or complete an unauthorized aa_replace_current_label(); failed builds are still rejected later, so integrity impact is limited to the read-side fault rather than modification or code execution.\nA:H - Dereferencing NULL or ERR_PTR labels in aa_label_is_unconfined_subset() causes a kernel BUG/oops/panic, yielding host-wide denial of service on AppArmor-enabled systems and repeatable crashes from the same procattr write."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["security/apparmor/domain.c"], "versions": [{"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "a29f06db44b4c94597ded58f639eed3e21781ac3", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "cfc224866530a6842b6c2d2d30ef6a9b0e64bb9c", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "31cb109db5e6322ed22304fd5c0dedbaa438d6d3", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "b7c45c05a396a017c49ac7949de240a0dfc0ac4e", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "d84bb195d208adbf77f012ca2a96e11163f6def1", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "d82160132345688a09cbaa648cfdd16bb32e8ea2", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "ec926b2a351eeeb31e6c9aee02e0c32f94b5588f", "status": "affected", "versionType": "git"}, {"version": "e00b02bb6ac2a1893227ce8014b649028d6425d2", "lessThan": "a58cafd38b46fb1a2220e2fbbcfe291ea75fa147", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["security/apparmor/domain.c"], "versions": [{"version": "4.13", "status": "affected"}, {"version": "0", "lessThan": "4.13", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.261", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.212", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.178", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.145", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.97", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.40", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.5", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2", "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": "4.13", "versionEndExcluding": "5.10.261"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "5.15.212"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "6.1.178"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "6.6.145"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "6.12.97"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "6.18.40"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "7.1.5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.13", "versionEndExcluding": "7.2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/a29f06db44b4c94597ded58f639eed3e21781ac3"}, {"url": "https://git.kernel.org/stable/c/cfc224866530a6842b6c2d2d30ef6a9b0e64bb9c"}, {"url": "https://git.kernel.org/stable/c/31cb109db5e6322ed22304fd5c0dedbaa438d6d3"}, {"url": "https://git.kernel.org/stable/c/b7c45c05a396a017c49ac7949de240a0dfc0ac4e"}, {"url": "https://git.kernel.org/stable/c/d84bb195d208adbf77f012ca2a96e11163f6def1"}, {"url": "https://git.kernel.org/stable/c/d82160132345688a09cbaa648cfdd16bb32e8ea2"}, {"url": "https://git.kernel.org/stable/c/ec926b2a351eeeb31e6c9aee02e0c32f94b5588f"}, {"url": "https://git.kernel.org/stable/c/a58cafd38b46fb1a2220e2fbbcfe291ea75fa147"}], "title": "apparmor: check label build before no_new_privs test", "x_generator": {"engine": "bippy-1.2.0"}}}}
