When the device is eventually unbound, mana_remove() is invoked\na second time. Without a NULL check, it dereferences gc->dev with\ngc == NULL, causing a kernel panic.\n\nAdd an early return if gdma_context or driver_data is NULL so the second\ninvocation is harmless. Move the dev = gc->dev assignment after the\nguard so it cannot dereference NULL."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/microsoft/mana/mana_en.c"],"versions":[{"version":"635096a86edb067d55a1e04b4a918f5c6dac0c51","lessThan":"a1ddfd2c0b7a48e5239fadd2a24cc4bc2cda90e6","status":"affected","versionType":"git"},{"version":"635096a86edb067d55a1e04b4a918f5c6dac0c51","lessThan":"bbe5c3c570645a4ceb120979d3ee203a1583d775","status":"affected","versionType":"git"},{"version":"635096a86edb067d55a1e04b4a918f5c6dac0c51","lessThan":"50271d7ec95144d26808025b508f463780517d3c","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/microsoft/mana/mana_en.c"],"versions":[{"version":"5.16","status":"affected"},{"version":"0","lessThan":"5.16","status":"unaffected","versionType":"semver"},{"version":"6.18.33","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.10","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"5.16","versionEndExcluding":"6.18.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"7.0.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a1ddfd2c0b7a48e5239fadd2a24cc4bc2cda90e6"},{"url":"https://git.kernel.org/stable/c/bbe5c3c570645a4ceb120979d3ee203a1583d775"},{"url":"https://git.kernel.org/stable/c/50271d7ec95144d26808025b508f463780517d3c"}],"title":"net: mana: Guard mana_remove against double invocation","x_generator":{"engine":"bippy-1.2.0"}}}}
