Proceed to\nath12k_dp_rx_peer_tid_delete() starting from unallocated tid,\nwhich might leads to freeing unallocated TID and cause potential\ncrash or out-of-bounds access.\n\nHence, fix by correctly decrementing tid before cleanup to match only\nthe successfully allocated TIDs.\n\nAlso, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),\nas decrementing the tid before cleanup in loop will take care of this.\n\nCompile tested only."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/ath/ath12k/dp.c"],"versions":[{"version":"d889913205cf7ebda905b1e62c5867ed4e39f6c2","lessThan":"30cad87978057516c93467516bc481a3eacfd66a","status":"affected","versionType":"git"},{"version":"d889913205cf7ebda905b1e62c5867ed4e39f6c2","lessThan":"2ef17d1476ab26bce89764e2f16833d7f52acc38","status":"affected","versionType":"git"},{"version":"d889913205cf7ebda905b1e62c5867ed4e39f6c2","lessThan":"907c630e58af9e86e215f3951c7b287bd86d0f15","status":"affected","versionType":"git"},{"version":"d889913205cf7ebda905b1e62c5867ed4e39f6c2","lessThan":"6301fe4f209165334d251a1c6da8ae47f93cb32c","status":"affected","versionType":"git"},{"version":"d889913205cf7ebda905b1e62c5867ed4e39f6c2","lessThan":"4a2bf707270f897ab8077baee8ed5842a5321686","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/ath/ath12k/dp.c"],"versions":[{"version":"6.3","status":"affected"},{"version":"0","lessThan":"6.3","status":"unaffected","versionType":"semver"},{"version":"6.6.103","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.43","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.11","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16.2","lessThanOrEqual":"6.16.*","status":"unaffected","versionType":"semver"},{"version":"6.17","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.6.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.12.43"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.15.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.16.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.17"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/30cad87978057516c93467516bc481a3eacfd66a"},{"url":"https://git.kernel.org/stable/c/2ef17d1476ab26bce89764e2f16833d7f52acc38"},{"url":"https://git.kernel.org/stable/c/907c630e58af9e86e215f3951c7b287bd86d0f15"},{"url":"https://git.kernel.org/stable/c/6301fe4f209165334d251a1c6da8ae47f93cb32c"},{"url":"https://git.kernel.org/stable/c/4a2bf707270f897ab8077baee8ed5842a5321686"}],"title":"wifi: ath12k: Correct tid cleanup when tid setup fails","x_generator":{"engine":"bippy-1.2.0"}}}}
