CVE-2026-98840
The Linux kernel is vulnerable to a Use-After-Free (UAF) condition within the vcs_write() function. The root cause is that the reload of the vc pointer occurs after an if (ret) block; consequently, a copy-failure break path can exit the loop without reloading the pointer. If the vc structure is f...

Linux Kernel Security Vulnerabilities
The Linux kernel has a security vulnerability. This vulnerability stems from vcswrite, which does not reload the vc pointer when the failed copying path is encountered. As a result, vcsnotifier reads memory that has been released, potentially leading to reuse of the released memory after it has...
