CVE-2026-99182

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-topology: Fix shift-out-of-bounds for aggregated ALH capture When chcount is smaller than blob->alhcfg.devicecount (e.g. a mono capture stream, such as a SmartMic, aggregated across multiple SDW links), step = chcount / blob->alhcfg.devicecount truncates to 0. The subsequent GENMASK(step - 1, 0) then underflows step - 1 (u32) to UINTMAX, 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 chcount < devicecount the same way as the existing "channels equal to output reference channels" case: apply the same chmask to every aggregated device instead of trying to split channels that can't be evenly divided.
