Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"http://xenbits.xen.org/xsa/advisory-362.html"},{"name":"FEDORA-2021-8d45d297c6","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQR52ICKRK3GC4HDWLMWF2U55YGAR63/"},{"name":"FEDORA-2021-7143aca8cb","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GWQWPWYZRXVFJI5M3VCM72X27IB7CKOB/"},{"name":"[debian-lts-announce] 20210309 [SECURITY] [DLA 2586-1] linux security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2021/03/msg00010.html"},{"url":"https://security.netapp.com/advisory/ntap-20210326-0001/"},{"name":"[debian-lts-announce] 20210330 [SECURITY] [DLA 2610-1] linux-4.19 security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2021/03/msg00035.html"},{"url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7c77474b2d22176d2bfb592ec74e0f2cb71352c9"},{"url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5a264285ed1cd32e26d9de4f3c8c6855e467fd63"},{"url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3194a1746e8aabe86075fd3c5e7cf1f4632d7f16"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T20:33:41.548Z"},"title":"CVE Program Container","references":[{"url":"http://xenbits.xen.org/xsa/advisory-362.html","tags":["x_transferred"]},{"name":"FEDORA-2021-8d45d297c6","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XQR52ICKRK3GC4HDWLMWF2U55YGAR63/"},{"name":"FEDORA-2021-7143aca8cb","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GWQWPWYZRXVFJI5M3VCM72X27IB7CKOB/"},{"name":"[debian-lts-announce] 20210309 [SECURITY] [DLA 2586-1] linux security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2021/03/msg00010.html"},{"url":"https://security.netapp.com/advisory/ntap-20210326-0001/","tags":["x_transferred"]},{"name":"[debian-lts-announce] 20210330 [SECURITY] [DLA 2610-1] linux-4.19 security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2021/03/msg00035.html"},{"url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7c77474b2d22176d2bfb592ec74e0f2cb71352c9","tags":["x_transferred"]},{"url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5a264285ed1cd32e26d9de4f3c8c6855e467fd63","tags":["x_transferred"]},{"url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3194a1746e8aabe86075fd3c5e7cf1f4632d7f16","tags":["x_transferred"]}]}]}}
