Linux Distros Unpatched Vulnerability : CVE-2026-45995

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: iouring/zcrx: fix userstruct uaf iofreerbufring usees a struct userstruct, which iozcrxifqfr...

CVE-2026-45995

A flaw was found in the Linux kernel's iouring/zcrx subsystem. This use-after-free UAF vulnerability occurs because the iofreerbufring function uses a struct userstruct that is prematurely freed by iozcrxifqfree before the ring is destroyed. A local attacker could potentially exploit this flaw to...
