CVE-2026-72068

A flaw was found in the Linux kernel's posix-cpu-timers component on 32-bit systems. An integer truncation vulnerability occurs in the updaterlimitcpu function when converting the RLIMITCPU value to nanoseconds. This issue causes the process CPU timer to be programmed to fire prematurely for...

CVE-2026-72068 posix-cpu-timers: Use u64 multiplication in update_rlimit_cpu()

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Use u64 multiplication in updaterlimitcpu updaterlimitcpu converts the RLIMITCPU value to nanoseconds with u64 nsecs = rlimnew NSECPERSEC; On 32-bit kernels both rlimnew unsigned long and NSECPERSEC 1000000000L...
