Hello! This is an experimental semi-automated report about issues detected by Coverity from a scan of next-20221202 as part of the linux-next scan project: https://scan.coverity.com/projects/linux-next-weekly-scan You're getting this email because you were associated with the identified lines of code (noted below) that were touched by commits: Thu Dec 1 17:29:14 2022 +0100 bd2404d42821 ("wifi: mt76: mt7915: add basedband Txpower info into debugfs") Coverity reported the following: *** CID 1527799: Resource leaks (RESOURCE_LEAK) drivers/net/wireless/mediatek/mt76/mt7915/debugfs.c:999 in mt7915_rate_txpower_get() 993 buf = kzalloc(sz, GFP_KERNEL); 994 if (!buf) 995 return -ENOMEM; 996 997 ret = mt7915_mcu_get_txpower_sku(phy, txpwr, sizeof(txpwr)); 998 if (ret) vvv CID 1527799: Resource leaks (RESOURCE_LEAK) vvv Variable "buf" going out of scope leaks the storage it points to. 999 return ret; 1000 1001 /* Txpower propagation path: TMAC -> TXV -> BBP */ 1002 len += scnprintf(buf + len, sz - len, 1003 "\nPhy%d Tx power table (channel %d)\n", 1004 phy != &dev->phy, phy->mt76->chandef.chan->hw_value); If this is a false positive, please let us know so we can mark it as such, or teach the Coverity rules to be smarter. If not, please make sure fixes get into linux-next. :) For patches fixing this, please include these lines (but double-check the "Fixes" first): Reported-by: coverity-bot <keescook+coverity-bot@xxxxxxxxxxxx> Addresses-Coverity-ID: 1527799 ("Resource leaks") Fixes: bd2404d42821 ("wifi: mt76: mt7915: add basedband Txpower info into debugfs") Thanks for your attention! -- Coverity-bot
