Description

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix Oops by 9.1 surround channel names get_line_out_pfx() may trigger an Oops by overflowing the static array with more than 8 channels. This was reported for MacBookPro 12,1 with Cirrus codec. As a workaround, extend for the 9.1 channels and also fix the potential Oops by unifying the code paths accessing the same array with the proper size check.

Affected configurations

• linux linux kernel (< 4.14.316) • linux linux kernel (>= 4.15 < 4.19.284) • linux linux kernel (>= 4.20 < 5.4.244) • linux linux kernel (>= 5.5 < 5.10.181) • linux linux kernel (>= 5.11 < 5.15.113) • linux linux kernel (>= 5.16 < 6.1.30) • linux linux kernel (>= 6.2 < 6.3.4) • linux linux kernel 6.4
