This pointer is stored\nin rng->priv and later consumed by the read path once the transaction\ncompletes.\n\nIf the underlying I2C transfer fails, the completion callback is invoked\nwith a non-zero status. In this case, the allocated work_data is not\nusable for producing RNG output and must not remain associated with the\nhwrng state.\n\nPreviously, the failure path only logged a warning but left the pointer\nstate uncleared, which can result in subsequent read attempts observing\nstale state and interpreting it as valid completion data.\n\nFix this by freeing the pending work_data. The I2C transaction reports\nan error. This ensures that failed requests do not leave residual state\nbehind that could be interpreted as valid RNG data on later reads.\nClearing rng->priv is done at the subsequent call to nonblocking read."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/crypto/atmel-sha204a.c"],"versions":[{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"a430b5b6d2ddd2b266330f8507a655be1148347d","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"4e76d85e505b7451925efbcd67c015e8c2440c68","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"bcac9052e19490231ff6e0678a06bd2fcf8db3af","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"28cc179252347718f97045dd5ea74165609dbd7d","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"0d6db386133d9230befb77967bbf130443964860","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"f4d347fb1309b69ea6f817a17e6b2893c8d754b7","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"94abda77b57a35b82bba0365bad072d94d67ffe9","status":"affected","versionType":"git"},{"version":"da001fb651b00e1deeaf24767dd691ae8152a4f5","lessThan":"72bbf11ba14bd7d5fbf31a1ec42fff608b657f74","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/crypto/atmel-sha204a.c"],"versions":[{"version":"5.3","status":"affected"},{"version":"0","lessThan":"5.3","status":"unaffected","versionType":"semver"},{"version":"5.10.270","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.221","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","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":"5.3","versionEndExcluding":"5.10.270"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"5.15.221"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a430b5b6d2ddd2b266330f8507a655be1148347d"},{"url":"https://git.kernel.org/stable/c/4e76d85e505b7451925efbcd67c015e8c2440c68"},{"url":"https://git.kernel.org/stable/c/bcac9052e19490231ff6e0678a06bd2fcf8db3af"},{"url":"https://git.kernel.org/stable/c/28cc179252347718f97045dd5ea74165609dbd7d"},{"url":"https://git.kernel.org/stable/c/0d6db386133d9230befb77967bbf130443964860"},{"url":"https://git.kernel.org/stable/c/f4d347fb1309b69ea6f817a17e6b2893c8d754b7"},{"url":"https://git.kernel.org/stable/c/94abda77b57a35b82bba0365bad072d94d67ffe9"},{"url":"https://git.kernel.org/stable/c/72bbf11ba14bd7d5fbf31a1ec42fff608b657f74"}],"title":"crypto: atmel-sha204a - fix heap info leak on I2C transfer failure","x_generator":{"engine":"bippy-1.2.0"}}}}
