CVE-2026-64370

A flaw was found in the Linux kernel's posix-cpu-timers component. This vulnerability allows a local user to trigger a resource leak within the docpunanosleep function. The issue occurs because a process identifier PID reference is not properly released if a timer creation operation fails. This...

CVE-2026-64560

CVE-2026-64560 documents a Linux kernel issue in posix-cpu-timers that can cause a Use-After-Free when a timer is deleted during a non-leader exec() race. The vulnerability arises as sys_timer_delete() may observe an old leader while a leader change occurs, leading to a freed posix timer object b...

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Fix pid refcount leak in docpunanosleep error path In docpunanosleep, posixcputimercreate takes a pid reference via getpid and stores it in timer.it.cpu.pid. If the subsequent posixcputimerset call fails, the...

CVE-2026-64370 posix-cpu-timers: Fix pid refcount leak in do_cpu_nanosleep() error path

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Fix pid refcount leak in docpunanosleep error path In docpunanosleep, posixcputimercreate takes a pid reference via getpid and stores it in timer.it.cpu.pid. If the subsequent posixcputimerset call fails, the...

CVE-2026-64370

The CVE-2026-64370 issue concerns the Linux kernel’s posix-cpu-timers. In do_cpu_nanosleep(), posix_cpu_timer_create() takes a pid reference via get_pid() and stores it in timer.it.cpu.pid. If posix_cpu_timer_set() fails, the function returns without calling posix_cpu_timer_del(), causing a pid r...

Linux Distros Unpatched Vulnerability : CVE-2026-64370

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - posix-cpu-timers: Fix pid refcount leak in docpunanosleep error path In docpunanosleep, posixcputimercreate takes a pid reference via getpid and stores it in...

CVE-2026-53180

A flaw was found in the Linux kernel's timer migration handling. An incorrect assumption in the tmigrhandleremotecpu function regarding local softirq path handling of CPU timers can lead to a livelock. This occurs when a timer expires after the local timer wheel advances but before remote handlin...
