CVE-2024-50195 is a vulnerability in the Linux kernel's posix-clock subsystem, specifically affecting the pc_clock_settime() function. It stems from a missing validation check for timespec64 struct's tv_sec and tv_nsec ranges, which could lead to invalid time values being passed to hardware drivers. Rated as Medium severity (CVSS 5.5), this local vulnerability (AV:L) has low attack complexity (AC:L) and requires low privileges (PR:L), potentially resulting in high availability impact (A:H) due to system instability or incorrect timekeeping. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
