  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nrtc: mpfs: fix unchecked devm_clk_get() error pointer in probe()\n\ndevm_clk_get(&pdev->dev, \"rtcref\")'s return value was passed straight\ninto clk_get_rate() without checking it for an error first, unlike the\n\"rtc\" clock a few lines above which is correctly checked with\nIS_ERR(). clk_get_rate() only guards against a NULL clk, not an error\npointer:\n\n\tif (!clk)\n\t\treturn 0;\n\t...\n\trate = clk_core_get_rate_recalc(clk->core);\n\nso if devm_clk_get() ever returns an error pointer here (for example\nERR_PTR(-EPROBE_DEFER), which is the normal, expected outcome if the\nclkcfg clock-provider this RTC depends on has not registered its\nclocks yet by the time this driver probes), clk_get_rate() dereferences\nthat error pointer instead of returning 0, crashing instead of letting\nprobe defer.\n\nCapture the clock in the existing 'clk' local and check it with\nIS_ERR() before calling clk_get_rate(), matching the handling already\nused for the \"rtc\" clock in this same function.",
