In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Fix memory leak in ath11kpeerrxfragsetup
cryptoallocshash() allocates resources, which should be released by cryptofreeshash(). When ath11kpeerfind() fails, there has memory leak. Add missing cryptofreeshash() to fix this.
