CVE-2026-68362
Overview
CVE-2026-68362 is a known-severity vulnerability. It was published on August 10, 2026.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix NULL pointer dereference in ath11k_hal_srng_access_begin
In ATH11K_QMI_EVENT_FW_READY, ATH11K_FLAG_REGISTERED is set
unconditionally even when ath11k_core_qmi_firmware_ready() fails.
This leaves the driver in an inconsistent state where
initialization is considered complete although the firmware ready
handling did not finish successfully. During the subsequent SSR,
the driver enters the restart path based on this incorrect state
and dereferences uninitialized srng members, resulting in a NULL
pointer dereference.
Call trace:
ath11k_hal_srng_access_begin+0xc/0x60 [ath11k] (P)
ath11k_ce_cleanup_pipes+0x17c/0x180 [ath11k]
ath11k_core_restart+0x40/0x168 [ath11k]
Fix this by:
- skipping firmware_ready if ATH11K_FLAG_REGISTERED is already set
- setting ATH11K_FLAG_REGISTERED only when firmware_ready succeeds
- setting ATH11K_FLAG_QMI_FAIL and aborting the FW_READY handling
on error
