CVE-2024-49930

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58

Description: The issue is related to an array out-of-bounds access in the SoC stats of the wifi: ath11k module. The ath11k soc dp stats::hal reo error array is defined with a maximum size of DP REO DST RING MAX. However, the ath11k dp process rx() function accesses this array using the REO destination SRNG ring ID, which is incorrect. This leads to out-of-bounds array access. The fix involves modifying the ath11k dp process rx() function to use the normal ring ID directly instead of the SRNG ring ID.

Recommendations: To resolve the issue, update the Linux kernel to version 6.6.58 or later. As a temporary workaround, consider modifying the ath11k dp process rx() function to use the normal ring ID directly instead of the SRNG ring ID to avoid out-of-bounds array access.
