A kernel pointer leak can be used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "name": "http://www.openwall.com/lists/oss-security/2021/03/06/1", "url": "http://www.openwall.com/lists/oss-security/2021/03/06/1" }, { "refsource": "MISC", "name": "https://bugzilla.suse.com/show_bug.cgi?id=1182716", "url": "https://bugzilla.suse.com/show_bug.cgi?id=1182716" }, { "refsource": "MISC", "name": "https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=688e8128b7a92df982709a4137ea4588d16f24aa", "url": "https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=688e8128b7a92df982709a4137ea4588d16f24aa" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20210309 [SECURITY] [DLA 2586-1] linux security update", "url": "https://lists.debian.org/debian-lts-announce/2021/03/msg00010.html" }, { "refsource": "MISC", "name": "https://blog.grimm-co.com/2021/03/new-old-bugs-in-linux-kernel.html", "url": "https://blog.grimm-co.com/2021/03/new-old-bugs-in-linux-kernel.html" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20210330 [SECURITY] [DLA 2610-1] linux-4.19 security update", "url": "https://lists.debian.org/debian-lts-announce/2021/03/msg00035.html" }, { "refsource": "MISC", "name": "http://packetstormsecurity.com/files/162117/Kernel-Live-Patch-Security-Notice-LSN-0075-1.html", "url": "http://packetstormsecurity.com/files/162117/Kernel-Live-Patch-Security-Notice-LSN-0075-1.html" }, { "refsource": "CONFIRM", "name": "https://security.netapp.com/advisory/ntap-20210409-0001/", "url": "https://security.netapp.com/advisory/ntap-20210409-0001/" } ] } }
