  "details": "In the Linux kernel, the following vulnerability has been resolved:  ASoC: SOF: ipc4-topology: Fix shift-out-of-bounds for aggregated ALH capture  When ch_count is smaller than blob-\u003ealh_cfg.device_count (e.g. a mono capture stream, such as a SmartMic, aggregated across multiple SDW links), step = ch_count / blob-\u003ealh_cfg.device_count truncates to 0. The subsequent GENMASK(step - 1, 0) then underflows step - 1 (u32) to UINT_MAX, causing GENMASK()'s internal shift to use an out-of-bounds exponent:    UBSAN: shift-out-of-bounds in sound/soc/sof/ipc4-topology.c:2363:13   shift exponent 18446744069414584384 is too large for 64-bit type 'long unsigned int'  Treat ch_count \u003c device_count the same way as the existing \"channels equal to output reference channels\" case: apply the same ch_mask to every aggregated device instead of trying to split channels that can't be evenly divided.",
