Since oct->props[i].netdev is still\nNULL at this point, the cleanup function liquidio_destroy_nic_device()\nwill fail to find and free the netdev, resulting in a memory leak.\n\nFix this by initializing oct->props[i].netdev before calling the queue\nsetup functions. This ensures that the netdev is properly accessible for\ncleanup in case of errors.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.","2026-03-18T18:16:00Z",{"cvss_v3.1":10},{"scope":11,"version":12,"baseScore":13,"attackVector":14,"baseSeverity":15,"vectorString":16,"integrityImpact":17,"userInteraction":17,"attackComplexity":18,"availabilityImpact":19,"privilegesRequired":18,"confidentialityImpact":17},"UNCHANGED","3.1",5.5,"LOCAL","MEDIUM","CVSS:3.1\u002FAV:L\u002FAC:L\u002FPR:L\u002FUI:N\u002FS:U\u002FC:N\u002FI:N\u002FA:H","NONE","LOW","HIGH",false,[22],"CWE-401",[24,25,26,27,28,29,30,31,32],"cpe:2.3:o:linux:linux_kernel:6.19:rc7:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc4:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc2:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc3:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc6:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc8:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc1:*:*:*:*:*:*","cpe:2.3:o:linux:linux_kernel:6.19:rc5:*:*:*:*:*:*",[34],"Linux Linux Kernel",[36,37,38,39,40,41,42],"https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002F1d4590fde856cb94bd9a46e795c29d8288c238fc","https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002F926ede0c85e1e57c97d64d9612455267d597bb2c","https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002Fa0e57c0b68c9e6f9a8fd7c1167861a5a730eb2f4","https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002Fbe109646cdaecab262f6276303b1763468c94378","https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002Fc0ed6c77ec34050971fd0df2a94dfdea66d09331","https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002Fc81a8515fb8c8fb5d0dbc21f48337494bf1d60df","https:\u002F\u002Fgit.kernel.org\u002Fstable\u002Fc\u002Fd028147ae06407cb355245db1774793600670169",0.28,0.00119,0.01737,null,{"timestamp":46,"automatable":48,"tech_impact":49,"exploitation":50,"cisa_decision":51,"cisa_remediation_timeline":52},"no","partial","none",{},"FSU",[54],{"name":55,"source":56,"tactics":57,"technique_id":59},"Exploitation for Privilege Escalation","attack_vector",[58],"privilege-escalation","T1068",[]]
