This is a PCI accelerator driver, not network-reachable.\nAC:L - The attacker can reliably trigger the OOB write by crafting a command chain that exhausts buffer space before the final slot. No race condition or special conditions required.\nPR:L - Requires opening the accelerator device file (/dev/accel/accel*). The ioctl has no DRM_MASTER requirement (flags=0), so any local user with device access can trigger it. No root or special capabilities needed.\nUI:N - No user interaction required. The attacker directly submits malicious commands through the DRM ioctl interface.\nS:U - The vulnerability stays within the kernel's security authority. No VM escape, IOMMU bypass, or sandbox boundary crossing is involved.\nC:H - The ~52-byte heap zero-fill corrupts adjacent kernel objects. This memory corruption can be leveraged through heap shaping to corrupt length fields or create UAF conditions, potentially enabling arbitrary memory reads.\nI:H - Out-of-bounds write of zeros into kernel heap memory corrupts adjacent objects. This can overwrite function pointers, metadata, or security-critical fields, potentially enabling code execution.\nA:H - The out-of-bounds memset corrupts kernel heap metadata and adjacent objects, reliably causing kernel crashes or oops when the corrupted data is subsequently accessed."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/accel/amdxdna/aie2_message.c"], "versions": [{"version": "13ae1a6000f7d8b09478e3128e87d45e89c7282f", "lessThan": "cca770d710d5e03bc814af585cd6975eb6d74074", "status": "affected", "versionType": "git"}, {"version": "3d32eb7a5ecff92d83a5fd34c45c171c17d3d5d0", "lessThan": "1110a949675ebd56b3f0286e664ea543f745801c", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/accel/amdxdna/aie2_message.c"], "versions": [{"version": "6.19.4", "lessThan": "6.19.7", "status": "affected", "versionType": "semver"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.19.4", "versionEndExcluding": "6.19.7"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/cca770d710d5e03bc814af585cd6975eb6d74074"}, {"url": "https://git.kernel.org/stable/c/1110a949675ebd56b3f0286e664ea543f745801c"}], "title": "accel/amdxdna: Fix out-of-bounds memset in command slot handling", "x_generator": {"engine": "bippy-1.2.0"}}}}
