In such environments, a remote attacker can trigger the vulnerability by sending specially crafted data to the service.

A malicious actor with access to the Valkey clusterbus port can exploit an input validation vulnerability by sending a specially crafted invalid clusterbus packet. This lack of validation for clusterbus ping extension packets can lead to an out-of-bounds read. Consequently, this may cause the system to crash, resulting in a Denial of Service (DoS).", "title": "redhat - https://access.redhat.com/hydra/rest/securitydata/csaf/RHSA-2026:5445.json" }, { "category": "other", "text": "0.00018", "title": "EPSS" }, { "category": "other", "text": "5.1", "title": "NCSC Score" }, { "category": "other", "text": "VENDOR FIX as product remediation category, There is product data available from source Certbundde", "title": "NCSC Score top increasing factors" }, { "category": "other", "text": "Is related to (a version of) an uncommon product, The value of the most recent EPSS score, Is related to a product by vendor Debian", "title": "NCSC Score top decreasing factors" }, { "category": "details", "text": "Severity: 3\n", "title": "Vendor assessment" } ], "product_status": { "fixed": [ "CSAFPID-5733667", "CSAFPID-5733668", "CSAFPID-5733669", "CSAFPID-5733670", "CSAFPID-5755170", "CSAFPID-5755171", "CSAFPID-5755172", "CSAFPID-5755173", "CSAFPID-5902058", "CSAFPID-5902059", "CSAFPID-5902060", "CSAFPID-5902061" ], "known_affected": [ "CSAFPID-5677451", "CSAFPID-5677452", "CSAFPID-5677453", "CSAFPID-5677454", "CSAFPID-1439319", "CSAFPID-2858634", "CSAFPID-2889545", "CSAFPID-3093047", "CSAFPID-5686899", "CSAFPID-5686900", "CSAFPID-3765460", "CSAFPID-3765463", "CSAFPID-5558428", "CSAFPID-5558429", "CSAFPID-5558430", "CSAFPID-5563952", "CSAFPID-5563953", "CSAFPID-5563954", "CSAFPID-5686894", "CSAFPID-5686895", "CSAFPID-5686896", "CSAFPID-5686897", "CSAFPID-5686898", "CSAFPID-1403561", "CSAFPID-5707843", "CSAFPID-5707844", "CSAFPID-5707845", "CSAFPID-5707846", "CSAFPID-5729824", "CSAFPID-5729825", "CSAFPID-5729826", "CSAFPID-5729827", "CSAFPID-5733330", "CSAFPID-2838783", "CSAFPID-5135189", "CSAFPID-5135190", "CSAFPID-5135191", "CSAFPID-5135192", "CSAFPID-5135193", "CSAFPID-5135194", "CSAFPID-5135195", "CSAFPID-5135196", "CSAFPID-5135197", "CSAFPID-5686893", "CSAFPID-1317174", "CSAFPID-1317175", "CSAFPID-1317177", "CSAFPID-1330300", "CSAFPID-5776457", "CSAFPID-1330299", "CSAFPID-5851648", "CSAFPID-5851649", "CSAFPID-5851650", "CSAFPID-5851651", "CSAFPID-5851652", "CSAFPID-5851653", "CSAFPID-5851654", "CSAFPID-5851655", "CSAFPID-5851656", "CSAFPID-5851657", "CSAFPID-5851658", "CSAFPID-5851659", "CSAFPID-5851660", "CSAFPID-5851661", "CSAFPID-5851662", "CSAFPID-5851663" ], "known_not_affected": [ "CSAFPID-1403556" ] }, "references": [ { "category": "external", "summary": "Source -
