CVE-2024-57953

Service interruption via RTC offset multiplication overflow

Published Feb 27, 2025 · Updated May 11, 2026

Integer overflow in the TPS6594 RTC driver in Linux kernel 6.8 through 6.12.12 and 6.13 through 6.13.1 allows local users to interrupt service. tps6594_rtc_set_offset() multiplies an attacker-controlled long offset by a roughly 118-million-tick constant before promotion to s64, so the intermediate value wraps. Reachability requires a 32-bit kernel with the TPS6594 RTC driver and local access to change the RTC calibration offset; no confidentiality or integrity impact is reported.
