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 4.18 through 5.10.16 as used by Xen. The backend allocation (aka be-alloc) mode of the drm_xen_front drivers was not meant to be a supported configuration but this wasn't stated accordingly in its support status entry.

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.

Bodong Zhao discovered a use-after-free in the Sun keyboard driver implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. CVE-2020-25669 It was discovered that the jfs file system implementation in the Linux kernel...

USN-4748-1 linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon vulnerabilities

It was discovered that the jfs file system implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to possibly cause a denial of service system crash. CVE-2020-27815 It was discovered that the memory management subsystem in the Linux kerne...

FreeBSD : FreeBSD -- Xen grant mapping error handling issues (5b8c6e1e-770f-11eb-b87a-901b0ef719ab)

Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failur...

CVE-2021-20252

A flaw was found in Red Hat 3scale API Management Platform 2. The 3scale backend does not perform preventive handling on user-requested date ranges in certain queries allowing a malicious authenticated user to submit a request with a sufficiently large date range to eventually yield an internal...
