How to fix?

Upgrade SLES:15.7 kernel-livepatch-6_4_0-150700_53_90-default to version 1-150700.15.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_53_90-default package and not the kernel-livepatch-6_4_0-150700_53_90-default package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: f_uac1_legacy: validate bRequest index in generic_{set,get}_cmd

generic_set_cmd() and generic_get_cmd() use the low nibble of ctrl->bRequest as an index into con->data[]:

u8 cmd = (ctrl-&gt;bRequest &amp; 0x0F);  /* 0 .. 15 */
...
con-&gt;data[cmd] = value;            /* OOB when cmd &gt;= 5 */

struct usb_audio_control (include/linux/usb/audio.h) declares data as a 5-element array, so indices 5 through 15 write (or read) up to 44 bytes past the end of the array on the heap.

A malicious USB host can craft a class-specific SET_CUR / GET_CUR request with an arbitrary bRequest value, triggering the out-of-bounds access from an IRQ completion handler with no further preconditions.

Add an ARRAY_SIZE() guard to both functions.
