Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.6.160, 6.12.113, 6.18.57, and 7.2.11. This vulnerability arises because a lock is not held when calling dmtablegetmodenewmap via doresume; concurrent ioctl operations on the same device may swap tables after dmswaptable but befor...

Red Hat: CVE-2026-98872: kernel: freevxfs: don't BUG() on unknown typed-extent type

In the Linux kernel, the following vulnerability has been resolved: freevxfs: don't BUG on unknown typed-extent type vxfsbmaptyped handles four typed-extent types and calls BUG in its default case, so an on-disk typed extent with any other type value crashes the kernel. It is reachable from...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 2.6.25. It arises because the memstick core uses waitforcompletiontimeout in memstickalloccard and memsticksetrwaddr to wait for completion of device identification and address configuration requests. After a timeout, the memstickdev structu...
