kernel: ip6_gre: Use cached t->net in ip6erspan_changelink()

A flaw was found in the Linux kernel's ip6gre module. An unprivileged user could exploit this vulnerability by migrating a network device, causing the ip6erspanchangelink function to incorrectly handle network namespace references. This error leads to a use-after-free condition when the original...

kernel: mm/huge_memory: update file PMD counter before folio_put()

A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...
