When clearing curr_xfer in the\ncombined sequence transfer loop, protect it with the spinlock to prevent\na race with the interrupt handler.\n\nProtect the curr_xfer clearing at the exit path of\ntegra_qspi_combined_seq_xfer() with the spinlock to prevent a race\nwith the interrupt handler that reads this field.\n\nWithout this protection, the IRQ handler could read a partially updated\ncurr_xfer value, leading to NULL pointer dereference or use-after-free.\n\n## Affected\n\n- `Linux >= 88db8bb7ed1bb474618acdf05ebd4f0758d244e2 < 9fa4262a80f751d14a6a39d2c03f57db68da2618`\n- `Linux >= 83309dd551cfd60a5a1a98d9cab19f435b44d46d < 762e2ce71c8f0238e9eaf05d14da803d9a24422f`\n- `Linux >= c934e40246da2c5726d14e94719c514e30840df8 < 712cde8d916889e282727cdf304a43683adf899e`\n- `Linux >= 551060efb156c50fe33799038ba8145418cfdeef < 6fd446178a610a48e80e5c5b487b0707cd01daac`\n- `Linux >= 01bbf25c767219b14c3235bfa85906b8d2cb8fbc < 3bc293d5b56502068481478842f57b3d96e432c7`\n- `Linux >= b4e002d8a7cee3b1d70efad0e222567f92a73000 < bf4528ab28e2bf112c3a2cdef44fd13f007781cd`\n- `Linux bb0c58be84f907285af45657c1d4847b960a12bf`\n- `Linux >= 6.17.13 < 6.18`\n- `Linux >= 5.15.198 < 5.15.200`\n- `Linux >= 6.1.160 < 6.1.163`\n- `Linux >= 6.6.120 < 6.6.124`\n- `Linux >= 6.12.63 < 6.12.70`\n- `Linux >= 6.18.2 < 6.18.10`\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":[]}
