An\nunprivileged socket can therefore submit a reserved OCF that aliases an\nallowlisted command modulo 128.\n\nA conforming controller should reject reserved opcodes. Nevertheless,\nthe security decision must apply to the opcode that will actually be\nsent, especially since controller-specific behavior is outside the host\nstack's control.\n\nReject OCF values that cannot be represented by the security filter\ninstead of aliasing them onto an unrelated command.\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 70b0a27bdde0cb524349c8261202c7c9393cf5e9`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 598686f5d65b9af2223ed9d22fadba16e09f6ca8`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < c1fd465ea1c5aef459f9bc3ac602b5353e0f536f`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 68f0bcc4e16e31ff8dbe6ca93116eb70d7b6ac44`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 320dedad15e8bbaecc8d2d7fd4189defb84caa85`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 173457fa3e99ef4188dd0fe63e4dee98d0e441a9`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 47d67ec424e63e61e9eb58633d43a9d58a1852b6`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < e93fad891c72deb84cae49430163b384ebcc92b1`\n- `Linux 2.6.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
