And indeed\nit will, some 0.4% of times this code is called.\n\nThen enqueue + 1 is an invalid pointer. It will crash the kernel right\naway or load some junk which may look like a link TRB and cause the real\nlink TRB to be replaced with a NOOP. This wouldn't end well.\n\nUse a functionally equivalent test which doesn't dereference the pointer\nand always gives correct result.\n\nSomething has crashed my machine twice in recent days while playing with\nan Etron HC, and a control transfer stress test ran for confirmation has\njust crashed it again. The same test passes with this patch applied."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/host/xhci-ring.c"],"versions":[{"version":"fbc0a0c7718a6cb1dc5e0811a4f88a2b1deedfa1","lessThan":"142273a49f2c315eabdbdf5a71c15e479b75ca91","status":"affected","versionType":"git"},{"version":"9258c9ed32294ce3a4b58c9d92fc49ba030d35c9","lessThan":"bce3055b08e303e28a8751f6073066f5c33a0744","status":"affected","versionType":"git"},{"version":"5e1c67abc9301d05130b7e267c204e7005503b33","lessThan":"0624e29c595b05e7a0e6d1c368f0a05799928e30","status":"affected","versionType":"git"},{"version":"5e1c67abc9301d05130b7e267c204e7005503b33","lessThan":"1ea050da5562af9b930d17cbbe9632d30f5df43a","status":"affected","versionType":"git"},{"version":"4725344ca645a98a9d8e45e25b01a2244de5b8aa","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/usb/host/xhci-ring.c"],"versions":[{"version":"6.13","status":"affected"},{"version":"0","lessThan":"6.13","status":"unaffected","versionType":"semver"},{"version":"6.6.89","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.26","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.14.5","lessThanOrEqual":"6.14.*","status":"unaffected","versionType":"semver"},{"version":"6.15","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":"6.6.66","versionEndExcluding":"6.6.89"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12.2","versionEndExcluding":"6.12.26"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.14.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.15"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/142273a49f2c315eabdbdf5a71c15e479b75ca91"},{"url":"https://git.kernel.org/stable/c/bce3055b08e303e28a8751f6073066f5c33a0744"},{"url":"https://git.kernel.org/stable/c/0624e29c595b05e7a0e6d1c368f0a05799928e30"},{"url":"https://git.kernel.org/stable/c/1ea050da5562af9b930d17cbbe9632d30f5df43a"}],"title":"usb: xhci: Fix invalid pointer dereference in Etron workaround","x_generator":{"engine":"bippy-1.2.0"}}}}
