CVE-2025-37997

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfilter: ipset: fix region locking in hash types<br /> <br /> Region locking introduced in v5.6-rc4 contained three macros to handle<br /> the region locks: ahash_bucket_start(), ahash_bucket_end() which gave<br /> back the start and end hash bucket values belonging to a given region<br /> lock and ahash_region() which should give back the region lock belonging<br /> to a given hash bucket. The latter was incorrect which can lead to a<br /> race condition between the garbage collector and adding new elements<br /> when a hash type of set is defined with timeouts.
