Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.10.1, as used with Xen up to version 4.14.x. The Linux kernel’s PV block backend expects the kernel thread handler to reset ring-xenblkd to NULL when the thread is stopped. However, the handler may not have enough time to execute if the...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel versions 2.6.39 through 5.10.16, as used in Xen. The block, net, and SCSI backends consider certain errors as ordinary bugs, which are deliberately designed to cause kernel crashes. For errors that may be influenced by guests such as memory exhaustion...

SUSE CVE-2007-5498

The Xen hypervisor block backend driver for Linux kernel 2.6.18, when running on a 64-bit host with a 32-bit paravirtualized guest, allows local privileged users in the guest OS to cause a denial of service host OS crash via a request that specifies a large number of blocks...

SUSE CVE-2021-26931

An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. 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'...

Debian DLA-2586-1 : linux security update

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2019-19318, CVE-2019-19813, CVE-2019-19816 'Team bobfuzzer' reported bugs in Btrfs that could lead to a use-after-free or heap buffer overflow, and...

An issue was discovered in the Linux kernel 2.6.39 through 5.10.16 as used in Xen. 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.

An issue was discovered in the Linux kernel 3.11 through 5.10.16 as used by Xen. To service requests to the PV backend the driver maps grant references provided by the frontend. In this process errors may be encountered. In one case an error encountered earlier might be discarded by later processing resulting in the caller assuming successful mapping and hence subsequent operations trying to access space that wasn't mapped. In another case internal state would be insufficiently updated preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.
