the vulnerable path is not reachable via network packets or adjacent-network protocols.\nAC:L - An attacker who can open the device fully controls the v4l2_framebuffer width/height/bytesperline values that overflow the allocation and can reliably set up a CSS stream first, so no conditions outside the attacker’s control are required.\nPR:L - Access only requires opening /dev/video* (typically video-group or camera-permission access); atomisp_open and the FPN ioctl path perform no CAP_SYS_ADMIN or root checks.\nUI:N - The attacker triggers the bug directly via ioctl with crafted framebuffer dimensions; no action by another user is required.\nS:U - The impact is kernel memory corruption within the host kernel’s security authority (local privilege escalation / DoS), not a VM, IOMMU, or other cross-boundary escape.\nC:H - The overflow yields a heap out-of-bounds write of attacker-supplied frame data into the undersized fpn_config buffer, which can be leveraged for arbitrary kernel memory disclosure.\nI:H - The nested height/width loops write past the undersized kvmalloc buffer with attacker-controlled contents, enabling heap corruption suitable for control-flow hijacking or arbitrary write primitives.\nA:H - The same out-of-bounds heap writes reliably cause kernel oops/panic, and a NULL stream also yields an immediate kernel crash on dereference." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/staging/media/atomisp/pci/sh_css_params.c" ], "versions": [ { "version": "a49d25364dfb9f8a64037488a39ab1f56c5fa419", "lessThan": "51b8dc5163d2ff2bf04019f8bf7e3bd0e75bb654", "status": "affected", "versionType": "git" }, { "version": "ad85094b293e40e7a2f831b0311a389d952ebd5e", "lessThan": "a560aeac2f2d284903b5900774765d7fc61547bc", "status": "affected", "versionType": "git" }, { "version": "ad85094b293e40e7a2f831b0311a389d952ebd5e", "lessThan": "a549517e4b761f3940011db30320cb8c9badde54", "status": "affected", "versionType": "git" }, { "version": "ad85094b293e40e7a2f831b0311a389d952ebd5e", "lessThan": "3ad290194bb06979367622e47357462836c1d3b4", "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/staging/media/atomisp/pci/sh_css_params.c" ], "versions": [ { "version": "4.12", "status": "affected" }, { "version": "5.8", "status": "affected" }, { "version": "0", "lessThan": "4.12", "status": "unaffected", "versionType": "semver" }, { "version": "4.18", "lessThan": "5.8", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.77", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.0.7", "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": "4.12", "versionEndExcluding": "4.18" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "5.15.77" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "6.0.7" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.8", "versionEndExcluding": "6.1" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/51b8dc5163d2ff2bf04019f8bf7e3bd0e75bb654" }, { "url": "https://git.kernel.org/stable/c/a560aeac2f2d284903b5900774765d7fc61547bc" }, { "url": "https://git.kernel.org/stable/c/a549517e4b761f3940011db30320cb8c9badde54" }, { "url": "https://git.kernel.org/stable/c/3ad290194bb06979367622e47357462836c1d3b4" } ], "title": "media: atomisp: prevent integer overflow in sh_css_set_black_frame()", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2022-50399", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2026-01-14T18:52:28.120652Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-190", "description": "CWE-190 Integer Overflow or Wraparound" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-01-14T18:53:06.477Z" } } ] } }
