In the Linux kernel, the following vulnerability has been resolved:

netfs: Fix overrun check in netfsextractuseriter()

Fix netfsextractuseriter() so that if ioviterextractpages() overfills pages[], then those pages don't get included in the iterator constructed at the end of the function. If there was an overfill, memory corruption has already happened.

In the Linux kernel, the following vulnerability has been resolved:

ipv6: fix possible infinite loop in fib6selectpath()

Found while auditing the same pattern Sashiko reported in rt6fillnode() [1]. Apply the same fix as commit f8d8ce1b515a ("ipv6: fix possible infinite loop in fib6infousesdev()").

Writers holding tb6lock can listdelrcu(&first->fib6siblings) without waiting for RCU readers; first->fib6siblings.next then still points into the old ring and this softirq-side walker never reaches &first->fib6siblings as its terminator. fib6purgert() always WRITEONCE()s first->fib6nsiblings to 0 before listdelrcu(), so an inside-loop check is a reliable detach signal.
