In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix out-of-bounds access in cxlcancelautoattach In cxlcancelautoattach, it assumes cxled-pos is a valid index for accessing p-targets. However, cxled-pos can be set to negative errno in cxlregionsorttargets if...

UBUNTU-CVE-2026-74273

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Block region delete during region creation Expand the range lock, rename it "regionslock", to disable region deletion in the critical period between constructregion and attachtarget, as well as the period between...

CVE-2026-74272

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Resolve region deletion races Sungwoo noticed that the sysfs trigger to delete a region may try to delete a region multiple times. It also has no exclusion relative to the kernel releasing the region via CXL root devi...

CVE-2026-74275

The CVE-2026-74275 entry is about the Linux kernel driver cxl/region where cxl_cancel_auto_attach() can access p->targets[] using a potentially negative index cxled->pos. The root cause is that cxled->pos may be set to a negative errno in cxl_region_sort_targets() if cxl_calc_interleave_...

CVE-2026-74273

CVE-2026-74273 affects the Linux kernel’s cxl/region logic. The fix expands the range lock and renames it to a new lock called regions_lock to disable region deletion during two critical windows: between construct_region() and attach_target(), and between device_add() and registering the remove a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fixed the cxlregion leak, and cleaned up targets when a region is deleted. When a region is deleted, any targets that were previously assigned to that region still hold references to it. To trigger the release of thos...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fixed the crash that occurred during decoder allocation. When the decoders of an intermediate port are exhausted by existing regions, and a new region is created with that port in its hierarchical path, the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: cxl/region: Fixed leakage in constructregion. The first call to sysfsupdategroup requires explicitly freeing the resource, as it is too early for cxlregioniomemrelease to be called...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fixed memregion leaks in devmcxladdregion. The mode verification was moved to createregion, before allocating the memregion, to avoid memregion leaks...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: cxl/region: Do not attempt cleanup after a failure in cxlRegionAttach. Commit 5e42bcbc3fef “cxl/region: Decrement -nrtargets in case of errors in cxlRegionAttach” attempted to prevent initialization errors when -nrtargets...

SUSE CVE-2026-31529

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix leakage in constructregion Failing the first sysfsupdategroup needs to explicitly kfree the resource as it is too early for cxlregioniomemrelease to do so...

CVE-2026-31529

A flaw was found in the Linux kernel's cxl/region component. This vulnerability involves a resource leakage within the constructregion function. When sysfsupdategroup fails, the resource is not explicitly freed, leading to a memory leak. This could potentially allow a local attacker to cause a...
