PT-2025-8810

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.0 Description A use-after-free bug was found in the Linux kernel, specifically in the padata reorder function. This issue can be triggered when the padata find next function is called after the pd object has...

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest under specific conditions can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.
