CVE-2026-46255

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dmaengine: fsl-edma: don&amp;#39;t explicitly disable clocks in .remove()<br /> <br /> The clocks in fsl_edma_engine::muxclk are allocated and enabled with<br /> devm_clk_get_enabled(), which automatically cleans these resources up,<br /> but these clocks are also manually disabled in fsl_edma_remove(). This<br /> causes warnings on driver removal for each clock:<br /> <br /> edma_module already disabled<br /> WARNING: CPU: 0 PID: 418 at drivers/clk/clk.c:1200 clk_core_disable+0x198/0x1c8<br /> [...]<br /> Call trace:<br /> clk_core_disable+0x198/0x1c8 (P)<br /> clk_disable+0x34/0x58<br /> fsl_edma_remove+0x74/0xe8 [fsl_edma]<br /> [...]<br /> ---[ end trace 0000000000000000 ]---<br /> edma_module already unprepared<br /> WARNING: CPU: 0 PID: 418 at drivers/clk/clk.c:1059 clk_core_unprepare+0x1f8/0x220<br /> [...]<br /> Call trace:<br /> clk_core_unprepare+0x1f8/0x220 (P)<br /> clk_unprepare+0x34/0x58<br /> fsl_edma_remove+0x7c/0xe8 [fsl_edma]<br /> [...]<br /> ---[ end trace 0000000000000000 ]---<br /> <br /> Fix these warnings by removing the unnecessary fsl_disable_clocks() call<br /> in fsl_edma_remove().
