[PATCH] coresight: tmc-etf: Fix global-out-of-bounds in tmc_update_etf_buffer()

by Sai Prakash Ranjan

commit 6f755e85c332 ("coresight: Add helper for inserting synchronization packets") removed trailing '\0' from barrier_pkt array and updated the call sites like etb_update_buffer() to have proper checks for barrier_pkt size before read but missed updating tmc_update_etf_buffer() which still reads barrier_pkt past the array size resulting in KASAN out-of-bounds bug. Fix this by adding a check for barrier_pkt size before accessing like it is done in etb_update_buffer().

【重要】カード情報更新のお知らせ

by Amazon.co.jp

請求先住所が変更鹿児島県西之表市の馬毛島への自衛隊基地建設を巡り、塩田康一知事がに終わったなって思い国に島周辺での海上ボーリング調査を許可したことは違法だとして、地元漁業者が許可の取り消しを求めた訴訟の判決で、鹿児島地裁（古谷健二郎裁判長）は24日、訴えを却下した。湾など限られた海域なら説得力もある訴訟かもしれないが　海洋地域調に終わったなって思い査だから　漁場はそこに限られた物じゃス感染症が拡大してないと言う判断でしょうね
