CVE-2026-74564

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfilter: xt_hashlimit: validate hashtable supports XT_HASHLIMIT_RATE_MATCH<br /> <br /> The XT_HASHLIMIT_RATE_MATCH flag mode changes the semantics of the<br /> dsthash_ent structure which represents an entry in the hashtable. There<br /> is a union area which uses a different layout to express the rate match<br /> mode.<br /> <br /> Update .checkentry path to validate the XT_HASHLIMIT_RATE_MATCH mode<br /> flag is requested by two or more different rules that refer to the same<br /> hashtable. Otherwise, uninitialized access to the burst field in the<br /> union is possible.<br /> <br /> Reject the use of the XT_HASHLIMIT_RATE_MATCH mode flag if set on by<br /> revision less than 3 too.
