the attacker then directly triggers the UAF by closing the descriptor.\nPR:L - The ioctl has no DRM authentication, master, root-only, or capability requirement and is available to an ordinary user granted normal accelerator-device access.\nUI:N - The attacker independently issues the allocation ioctl and closes the descriptor; no action by another user is required.\nS:U - The dangling BO corrupts or exposes resources within the same host-kernel security authority and does not itself cross a VM or IOMMU isolation boundary.\nC:H - The freed BO can be reclaimed and sprayed before list traversal, making its reservation and other pointer fields attacker-influenced; this kernel-heap UAF can support arbitrary kernel-memory disclosure.\nI:H - Traversal performs locking and possible unbinding through attacker-influenced freed-object pointers, making arbitrary kernel writes or control-flow hijacking defensible.\nA:H - The stale BO is dereferenced during context teardown, producing the documented kernel page fault; controlled reallocation can also corrupt the list and cause an unbounded teardown loop."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/accel/ivpu/ivpu_gem.c"], "versions": [{"version": "8d88e4cdce4f5c56de55174a4d32ea9c06f7fa66", "lessThan": "9ad57ebd1249c7bbfe9a07ff5e0176dfa320cd62", "status": "affected", "versionType": "git"}, {"version": "8d88e4cdce4f5c56de55174a4d32ea9c06f7fa66", "lessThan": "8172838a284c27190fa6782c2740a97020434750", "status": "affected", "versionType": "git"}, {"version": "8d88e4cdce4f5c56de55174a4d32ea9c06f7fa66", "lessThan": "c9ef5ccd8bd9bcf598b6d3f77e7eb4dde7149aec", "status": "affected", "versionType": "git"}, {"version": "8d88e4cdce4f5c56de55174a4d32ea9c06f7fa66", "lessThan": "8b694b405a84696f1d964f6da7cf9721e68c4714", "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/accel/ivpu/ivpu_gem.c"], "versions": [{"version": "6.8", "status": "affected"}, {"version": "0", "lessThan": "6.8", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.114", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.17.13", "lessThanOrEqual": "6.17.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.2", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.19", "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": "6.8", "versionEndExcluding": "6.12.114"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.8", "versionEndExcluding": "6.17.13"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.8", "versionEndExcluding": "6.18.2"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.8", "versionEndExcluding": "6.19"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/9ad57ebd1249c7bbfe9a07ff5e0176dfa320cd62"}, {"url": "https://git.kernel.org/stable/c/8172838a284c27190fa6782c2740a97020434750"}, {"url": "https://git.kernel.org/stable/c/c9ef5ccd8bd9bcf598b6d3f77e7eb4dde7149aec"}, {"url": "https://git.kernel.org/stable/c/8b694b405a84696f1d964f6da7cf9721e68c4714"}], "title": "accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context()", "x_generator": {"engine": "bippy-1.2.0"}}}}
