Design/Logic Flaw

A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nftablesapi.c. Mishandled error handling with NFTMSGNEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local...

Design/Logic Flaw

A use-after-free vulnerability in the Linux Kernel iouring subsystem can be exploited to achieve local privilege escalation. Racing a iouring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59...
