Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
posix-cpu-timers: Fix pid refcount leak in do_cpu_nanosleep() error path<br />
<br />
In do_cpu_nanosleep(), posix_cpu_timer_create() takes a pid reference<br />
via get_pid() and stores it in timer.it.cpu.pid. If the subsequent<br />
posix_cpu_timer_set() call fails, the function returns immediately<br />
without calling posix_cpu_timer_del() to release the pid reference,<br />
causing a leak.<br />
<br />
Fix it by calling posix_cpu_timer_del() before the unlock-and-return<br />
on the error path, consistent with the other exit paths in the same<br />
function.
