 A microcode update has been released for Intel processors, addressing multiple vulnerabilties which potentially could cause information disclosue or local DoS.

 CVE-2024-23984

 Observable discrepancy in RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

 CVE-2024-24968

 Improper finite state machines (FSMs) in hardware logic in some Intel(R) Processors may allow an privileged user to potentially enable a denial of service via local access.

 For Debian 11 bullseye, these problems have been fixed in version 3.20240910.1~deb11u1.

 We recommend that you upgrade your intel-microcode packages.
