Only cyclic descriptors were handled, leaving non-cyclic\ndescriptors and their LLI chains to be permanently leaked.\n\nFix by using vchan_terminate_vdesc() which handles both cyclic and\nnon-cyclic descriptors by adding them to desc_terminated queue for\nproper cleanup.\n\nAdd pchan->desc != pchan->done check to prevent double-adding completed\ndescriptors, which would corrupt the list."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/dma/sun6i-dma.c"],"versions":[{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"bb87440561eb72b47a2b848b5373b86433b247e6","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"004a7a02982bed0a727a4ac7be400f00f353e7a2","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"b150f603083cc8b72b0cbf13ec3e91f85b4390a0","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"27806fe7b9701af0963dcd510e30e7d0cc314c43","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"1ccc5c059d067c5358682ad5352e7d7e9239ed9b","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"9086b488f2737d5dcee86852b83f2059f1cdfabf","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"d4ba6aa65fcd797152d3aebd428a7b2da49cd5eb","status":"affected","versionType":"git"},{"version":"555859308723d8d5b828304f5eb9281143fd86b5","lessThan":"ab1150115e68a46b687eb38c1ab92782018c9f2c","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/dma/sun6i-dma.c"],"versions":[{"version":"3.17","status":"affected"},{"version":"0","lessThan":"3.17","status":"unaffected","versionType":"semver"},{"version":"5.10.265","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.216","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.183","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.151","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.103","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.44","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.8","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"3.17","versionEndExcluding":"5.10.265"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"5.15.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"6.1.183"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"6.6.151"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"6.12.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"6.18.44"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"7.1.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.17","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bb87440561eb72b47a2b848b5373b86433b247e6"},{"url":"https://git.kernel.org/stable/c/004a7a02982bed0a727a4ac7be400f00f353e7a2"},{"url":"https://git.kernel.org/stable/c/b150f603083cc8b72b0cbf13ec3e91f85b4390a0"},{"url":"https://git.kernel.org/stable/c/27806fe7b9701af0963dcd510e30e7d0cc314c43"},{"url":"https://git.kernel.org/stable/c/1ccc5c059d067c5358682ad5352e7d7e9239ed9b"},{"url":"https://git.kernel.org/stable/c/9086b488f2737d5dcee86852b83f2059f1cdfabf"},{"url":"https://git.kernel.org/stable/c/d4ba6aa65fcd797152d3aebd428a7b2da49cd5eb"},{"url":"https://git.kernel.org/stable/c/ab1150115e68a46b687eb38c1ab92782018c9f2c"}],"title":"dmaengine: sun6i-dma: Fix reclaim descriptors while terminating DMA","x_generator":{"engine":"bippy-1.2.0"}}}}
