This is because when the control flow\ngoes to the label free_eth_finfo, only the allocations starting from\n(i-1)th iteration are freed.\n\nFix that by freeing the loc_array in the bmap allocation error path.\n\n## Affected\n\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < e9de08e15aee35b96064960f95997bb6c1209c4b`\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < 118d05b530343cd9322607b9719405ba254a4183`\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < fa2d7708955e4f8212fd69bab1da604e60cb0b15`\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < 08aa59c0be768596467552c129e9f82166779a67`\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < dafb6e433ab2333b67be05433dc9c6ccbc7b1284`\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < 76deedea08899885f076aba0bb80bd1276446822`\n- `Linux >= d915c299f1da68a7dbb43895b8741c7b916c9d08 < 00ffb3724ce743578163f5ade2884374554ca021`\n- `Linux 5.9`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
