Linux Distros Unpatched Vulnerability : CVE-2026-90310

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - xen/xenbus: check otherendid only after it has been initialized When device just got initialized for example on module load, the otherendid field is initialized...

DEBIAN-CVE-2026-90310

In the Linux kernel, the following vulnerability has been resolved: xen/xenbus: check otherendid only after it has been initialized When device just got initialized for example on module load, the otherendid field is initialized only after xenbusreadotherenddetails gets called. If xenstore watch...

CVE-2026-90310

CVE-2026-90310 affects the Linux kernel 's xen/xenbus driver. A race condition exists where the xenstore watch thread (xenwatch ) can trigger xenbus_dev_changed() before the otherend_id field is initialized during device probe (e.g., on module load). The still-zeroed otherend_id is then misinterp...

ROS-20260916-73-0028

The vulnerability of the buildidshow function in the drivers/xen/privcmd.c module of the Linux kernel device driver library is related to the re-release of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: xen/netfront: Destroy queues before realnumtxqueues is zeroed xennetDestroyQueues relies on info-netdev-realnumtxqueues to delete queues. Since d7dac083414eb5bb99a6d2ed53dc2c1b405224e5 “net-sysfs: Update the queue counts in the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/amdnb: The rdmsrsafe function was used in amdgetmmconfigrange. Xen does not provide the MSRFAM10HMMIOCONFbase to all guests. This results in the following warning: Unchecked MSR access error: RDMSR from 0xc0010058 at rIP:...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

Closing an event channel in the Linux kernel can lead to a deadlock. This occurs when the closure operation is performed in parallel with an unrelated Xen console action, and the handling of a Xen console interrupt occurs in a unprivileged guest. The closure of an event channel is triggered, for...

Astra Linux – Vulnerability in Xen

A issue was discovered in Xen versions 4.9 through 4.14.x. On the ARM architecture, a guest can control whether memory accesses bypass the cache. This means that Xen needs to ensure that all writes such as those during scrubbing have reached the memory before handing over the page to the guest...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xen-netfront: Added the missing skbmarkforrecycle function. It should be noted that the skbmarkforrecycle function was introduced later than the “fixes” tag in commit 6a5bcd84e886 “pagepool: Allow drivers to hint on SKB recycling...

Astra Linux – Vulnerability in Xen

Potential speculative code storage bypasses exist in all supported CPU products. Combined with software vulnerabilities related to speculative execution of overwritten instructions, this could lead to incorrect speculation and potentially cause data leakage...

Astra Linux – Vulnerability in Xen

Inappropriate x86 IOMMU timeout detection/handling: IOMMU processes commands that are issued in parallel with the operation of the CPUs that issue those commands. In the current implementation in Xen, asynchronous notifications of the completion of such commands are not used. Instead, the issuing...

Transmitted requests in Xen’s virtual network protocol can consist of multiple parts. Although none of them are actually useful, except for the initial part, any of these parts can be of zero length, meaning they carry no data at all. Apart from the certain initial portion of the data to be...

Astra Linux – Vulnerability in Xen

A issue was discovered in Xen through version 4.11.x, allowing users of x86 Intel HVM guest operating systems to obtain unintended read/write DMA access. This could potentially lead to a denial of service host operating system crash or privilege escalation. This issue arises because a backport...
