No race or condition outside the attacker's practical influence is required.\nPR:N - LIO supports AuthMethod=None and dynamic initiator ACLs, allowing a remote attacker to establish a normal iSCSI session without credentials in a reasonable permissive deployment.\nUI:N - Exploitation requires only attacker-generated sessions and SCSI commands, without any victim action.\nS:U - Through the network iSCSI path, the vulnerable target-core code and the affected kernel availability remain within the same host security authority.\nC:N - The failed allocation produces a fixed NULL destination rather than an attacker-controlled read primitive, and no kernel data is disclosed.\nI:N - The attempted copy targets unmapped address zero and faults instead of modifying a live kernel object; it does not provide an arbitrary or useful write primitive.\nA:H - The NULL-destination memcpy can cause a kernel oops or panic, and a remote initiator can repeat the trigger to disrupt the target or entire system."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/target/target_core_transport.c"],"versions":[{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"6cac97b12bdab04832e0416d049efcd0d48d303b","status":"affected","versionType":"git"},{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"45fd86b444105c8bd07a763f58635c87e5dc7aea","status":"affected","versionType":"git"},{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"8727663ded659aad55eef21e3864ebf5a4796a96","status":"affected","versionType":"git"},{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"0260ad551b0815eb788d47f32899fbcd65d6f128","status":"affected","versionType":"git"},{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"0d36db68fdb8a3325386fd9523b67735f944e1f3","status":"affected","versionType":"git"},{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"8edbb9e371af186b4cf40819dab65fafe109df4d","status":"affected","versionType":"git"},{"version":"9e95fb805dc043cc8ed878a08d1583e4097a5f80","lessThan":"5053eab38a4c4543522d0c320c639c56a8b59908","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/target/target_core_transport.c"],"versions":[{"version":"5.8","status":"affected"},{"version":"0","lessThan":"5.8","status":"unaffected","versionType":"semver"},{"version":"5.10.248","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.198","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.160","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.120","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.64","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.3","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"5.10.248"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"5.15.198"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.1.160"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.6.120"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.12.64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.18.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.8","versionEndExcluding":"6.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6cac97b12bdab04832e0416d049efcd0d48d303b"},{"url":"https://git.kernel.org/stable/c/45fd86b444105c8bd07a763f58635c87e5dc7aea"},{"url":"https://git.kernel.org/stable/c/8727663ded659aad55eef21e3864ebf5a4796a96"},{"url":"https://git.kernel.org/stable/c/0260ad551b0815eb788d47f32899fbcd65d6f128"},{"url":"https://git.kernel.org/stable/c/0d36db68fdb8a3325386fd9523b67735f944e1f3"},{"url":"https://git.kernel.org/stable/c/8edbb9e371af186b4cf40819dab65fafe109df4d"},{"url":"https://git.kernel.org/stable/c/5053eab38a4c4543522d0c320c639c56a8b59908"}],"title":"scsi:
