Description SMASH SMASH 2024-05-23 08:14:13 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps()

reg_cap.phy_id is extracted from WMI event and could be an unexpected value
in case some errors happen. As a result out-of-bound write may occur to
soc->hal_reg_cap. Fix it by validating reg_cap.phy_id before using it.

This is found during code review.

Compile tested only.

Comment 2 Takashi Iwai 2024-05-24 17:01:46 UTC 
cve/linux-5.14 and earlier don't contain ath12 driver at all, hence unaffected.
Reassigned back.
Comment 3 Andrea Mattiazzo 2024-05-29 12:11:37 UTC 
All done, closing.
