CVE-2026-64253

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> kernel/fork: clear PF_BLOCK_TS in copy_process()<br /> <br /> PF_BLOCK_TS is only set in blk_time_get_ns() when current-&gt;plug is<br /> non-NULL, and blk_finish_plug() clears it via __blk_flush_plug()<br /> before NULLing the plug pointer. copy_process() breaks the<br /> invariant by inheriting PF_BLOCK_TS from the parent while resetting<br /> the child&amp;#39;s plug to NULL.<br /> <br /> Clear PF_BLOCK_TS alongside that assignment so callers can rely on<br /> "PF_BLOCK_TS set implies current-&gt;plug != NULL" and dereference<br /> current-&gt;plug unguarded.
