However, only 'page_dma' was actually initialized and used\nto program the Rx descriptor. But 'dma' was uninitialized and used in\nsome paths.\n\nThis could lead to undefined behavior, including DMA errors or\nuse-after-free, if the uninitialized 'dma' was used. Althrough such\nerror has not yet occurred, it is worth fixing in the code."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/wangxun/libwx/wx_lib.c","drivers/net/ethernet/wangxun/libwx/wx_type.h"],"versions":[{"version":"3c47e8ae113a68da47987750d9896e325d0aeedd","lessThan":"027701180a7bcb64c42eab291133ef0c87b5b6c5","status":"affected","versionType":"git"},{"version":"3c47e8ae113a68da47987750d9896e325d0aeedd","lessThan":"ba7c793f96c1c2b944bb6f423d7243f3afc30fe9","status":"affected","versionType":"git"},{"version":"3c47e8ae113a68da47987750d9896e325d0aeedd","lessThan":"05c37b574997892a40a0e9b9b88a481566b2367d","status":"affected","versionType":"git"},{"version":"3c47e8ae113a68da47987750d9896e325d0aeedd","lessThan":"5fd77cc6bd9b368431a815a780e407b7781bcca0","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/ethernet/wangxun/libwx/wx_lib.c","drivers/net/ethernet/wangxun/libwx/wx_type.h"],"versions":[{"version":"6.3","status":"affected"},{"version":"0","lessThan":"6.3","status":"unaffected","versionType":"semver"},{"version":"6.6.100","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.40","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.8","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16","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":"6.6.100"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.12.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.15.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3","versionEndExcluding":"6.16"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/027701180a7bcb64c42eab291133ef0c87b5b6c5"},{"url":"https://git.kernel.org/stable/c/ba7c793f96c1c2b944bb6f423d7243f3afc30fe9"},{"url":"https://git.kernel.org/stable/c/05c37b574997892a40a0e9b9b88a481566b2367d"},{"url":"https://git.kernel.org/stable/c/5fd77cc6bd9b368431a815a780e407b7781bcca0"}],"title":"net: libwx: fix the using of Rx buffer DMA","x_generator":{"engine":"bippy-1.2.0"}}}}
