BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 27.9%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
