This can be leveraged by an attacker to bypass executability restrictions of kernel-mode pages from user-mode. An incorrect setting of PXN bits within mmu_flags_to_s1_pte_attr lead to unprivileged executable pages being mapped as executable from a privileged context. This can be leveraged by an attacker to bypass executability restrictions of user-mode pages from kernel-mode. Typically this allows a potential attacker to circumvent a mitigation, making exploitation of potential kernel-mode vulnerabilities easier. We recommend updating kernel beyond commit 7d731b4e9599088ac3073956933559da7bca6a00 and rebuilding.","An incorrect setting of UXN bits within mmu_flags_to_s1_pte_attr lead to privileged executable pages being mapped as executable from an unprivileged context....","2022-01-18T14:15:07.92","2024-05-29T20:15:10.247",9.8,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":27,"CVSSMetricV2":30,"CVSSMetricV40":27},[16],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":28,"ImpactScore":29},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":25,"AvailabilityImpact":25,"BaseScore":12,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":25,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},"3.1","NETWORK","LOW","NONE","UNCHANGED","HIGH","CRITICAL",null,3.9,5.9,[31],{"Source":17,"Type":18,"CVSSData":32,"BaseSeverity":25,"ExploitabilityScore":37,"ImpactScore":38,"ACInsufInfo":27,"ObtainAllPrivilege":27,"ObtainUserPrivilege":27,"ObtainOtherPrivilege":27,"UserInteractionRequired":27},{"Version":33,"VectorString":34,"AccessVector":21,"AccessComplexity":22,"Authentication":23,"ConfidentialityImpact":35,"IntegrityImpact":35,"AvailabilityImpact":35,"BaseScore":36,"BaseSeverity":27,"Exploitability":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"CollateralDamagePotential":27,"TargetDistribution":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":27,"EnvironmentalScore":27},"2.0","AV:N\u002FAC:L\u002FAu:N\u002FC:P\u002FI:P\u002FA:P","PARTIAL",7.5,10,6.4,0.00294,[39,39,39,39,39,39,39],"Critical",[43],{"vendor":44,"product":45,"version":46,"criteria":47,"vulnerable":4},"google","fuchsia","-","cpe:2.3:o:google:fuchsia:-:*:*:*:*:*:*:*",1,[50],{"url":51,"source":52,"tags":53},"https:\u002F\u002Ffuchsia.googlesource.com\u002Ffuchsia\u002F+\u002F7d731b4e9599088ac3073956933559da7bca6a00","Googlesource",[54,55,56],"Mailing List","Patch","Third Party Advisory",[58],{"id":59,"name":60,"description":61,"extendedDescription":62,"status":63,"abstraction":64,"structure":65},"CWE-732","Incorrect Permission Assignment for Critical Resource","The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.","When a resource is given a permission setting that provides access to a wider range of actors than required, it could lead to the exposure of sensitive information, or the modification of that resource by unintended parties.
