[PATCH OLK-6.6] ALSA: usb-audio: Fix out of bounds reads when finding clock sources
by Luo Gengkun 28 Dec '24

28 Dec '24

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.64 commit 74cb86e1006c5437b1d90084d22018da30fddc77 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHGG CVE: CVE-2024-53150 Reference: https://git.kernel.org/stable/c/74cb86e1006c5437b1d90084d22018da30fddc77 -------------------------------- commit a3dd4d63eeb452cfb064a13862fb376ab108f6a6 upstream. The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.

[PATCH OLK-6.6] ALSA: usb-audio: Fix out of bounds reads when finding clock sources
by Luo Gengkun 28 Dec '24

28 Dec '24

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.64 commit 74cb86e1006c5437b1d90084d22018da30fddc77 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHGG CVE: CVE-2024-53150 Reference: https://git.kernel.org/stable/c/74cb86e1006c5437b1d90084d22018da30fddc77 commit a3dd4d63eeb452cfb064a13862fb376ab108f6a6 upstream. The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.
