The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-400" } ] } ] }, "references": { "reference_data": [ { "name": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2b04e8f6bbb196cab4b232af0f8d48ff2c7a8058", "refsource": "CONFIRM", "url": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2b04e8f6bbb196cab4b232af0f8d48ff2c7a8058" }, { "name": "101911", "refsource": "BID", "url": "http://www.securityfocus.com/bid/101911" }, { "name": "[debian-lts-announce] 20171210 [SECURITY] [DLA 1200-1] linux security update", "refsource": "MLIST", "url": "https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html" }, { "name": "USN-3583-2", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3583-2/" }, { "name": "RHSA-2018:1854", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:1854" }, { "name": "USN-3582-1", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3582-1/" }, { "name": "http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.13.8", "refsource": "CONFIRM", "url": "http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.13.8" }, { "name": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=95d78c28b5a85bacbc29b8dba7c04babb9b0d467", "refsource": "CONFIRM", "url": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=95d78c28b5a85bacbc29b8dba7c04babb9b0d467" }, { "name": "RHSA-2018:1062", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:1062" }, { "name": "https://github.com/torvalds/linux/commit/95d78c28b5a85bacbc29b8dba7c04babb9b0d467", "refsource": "CONFIRM", "url": "https://github.com/torvalds/linux/commit/95d78c28b5a85bacbc29b8dba7c04babb9b0d467" }, { "name": "RHSA-2018:0654", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:0654" }, { "name": "USN-3583-1", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3583-1/" }, { "name": "https://bugzilla.redhat.com/show_bug.cgi?id=1495089", "refsource": "CONFIRM", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=1495089" }, { "name": "https://github.com/torvalds/linux/commit/2b04e8f6bbb196cab4b232af0f8d48ff2c7a8058", "refsource": "CONFIRM", "url": "https://github.com/torvalds/linux/commit/2b04e8f6bbb196cab4b232af0f8d48ff2c7a8058" }, { "name": "http://seclists.org/oss-sec/2017/q4/52", "refsource": "CONFIRM", "url": "http://seclists.org/oss-sec/2017/q4/52" }, { "name": "RHSA-2018:0676", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:0676" }, { "name": "USN-3582-2", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3582-2/" } ] } }
