ALSA: control: Validate buf_len before strnlen() in snd_ctl_elem_init_enum_names()

2026-04-14T13:31:10+00:00

snd_ctl_elem_init_enum_names() advances pointer p through the names buffer while decrementing buf_len. If buf_len reaches zero but items remain, the next iteration calls strnlen(p, 0). While strnlen(p, 0) returns 0 and would hit the existing name_len == 0 error path, CONFIG_FORTIFY_SOURCE's fortified strnlen() first checks maxlen against __builtin_dynamic_object_size(). When Clang loses track of p's object size inside the loop, this triggers a BRK exception panic before the return value is examined. Add a buf_len == 0 guard at the loop entry to prevent calling fortified strnlen() on an exhausted buffer. Found by kernel fuzz testing through Xiaomi Smartphone.

ALSA: usb-audio: Fix missing error handling for get_min_max*()

2026-04-14T10:30:51+00:00

The recent fix to add the error return value check from get_min_max*() missed one case in build_audio_procunit() where no error value is set. This may lead to an uninitialized variable and confuse the caller (although this wouldn't happen practically because err is set for the loop of num_ins at the beginning of the funciton). Fix it by setting "err = 0" properly at the missing case, too.

ALSA: hda/realtek: Add quirk for Acer PT316-51S headset mic

The Acer PT316-51S (PCI SSID 1025:160e) with ALC287 codec does not detect the headset microphone due to missing BIOS pin configuration for pin 0x19. Apply ALC2XX_FIXUP_HEADSET_MIC to enable it.

ASoC: Updates for v7.1 There's one new core feature here but mostly this has been a fairly quiet release, we've got a few new drivers and one core feature that's likely to be relatively rarely used but the bulk of the work this time around has been on quality. - Support for bus keepers, this will be used by the Apple device support. - Enhancements to the SDCA support, incuding retaskable jacks. - Unwinding of the pcm_new()/pcm_free() cleanups from Morimoto-san. - Test improvements for the Cirrus Logic drivers. - Large sets of fixes for the NXP, nVidia and Qualcomm drivers. - Support for AMD RPL DMICs, Cirrus Logic CS42L43 and CS47L47, nVidia machines with CPCAP and WM8962.
