Even though the code setting the flag\nis designed to prevent it, there are subtle cases where the flag could be\ntrue at the mutex_lock stage and false at the mutex_unlock stage. This\nresults in the mutex not being unlocked, resulting in a deadlock.\n\nFix it by making the opt3001_irq() code generally more robust, reading the\nflag into a variable and using the variable value at both stages."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/iio/light/opt3001.c"],"versions":[{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"a9c56ccb7cddfca754291fb24b108a5350a5fbe9","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"957e8be112636d9bc692917286e81e54bd87decc","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"1d7def97e7eb65865ccc01bbdf4eb9e6bbe8a5b5","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"748ebd8e61d0bc182c331b8df3887af7285c8a8f","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"e791bf216c9e236b34dabf514ec0ede140cca719","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"7ca84f6a22d50bf8b31efe9eb05f9859947266d7","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"2c95c8f0959d0a72575eabf2ff888f47ed6d8b77","status":"affected","versionType":"git"},{"version":"94a9b7b1809f56cfaa080e70ec49b6979563a237","lessThan":"f063a28002e3350088b4577c5640882bf4ea17ea","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/iio/light/opt3001.c"],"versions":[{"version":"4.3","status":"affected"},{"version":"0","lessThan":"4.3","status":"unaffected","versionType":"semver"},{"version":"5.4.299","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.243","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.192","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.151","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.105","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.30","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.14.7","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":"4.3","versionEndExcluding":"5.4.299"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"5.10.243"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"5.15.192"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"6.1.151"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"6.6.105"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"6.12.30"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"6.14.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.3","versionEndExcluding":"6.15"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a9c56ccb7cddfca754291fb24b108a5350a5fbe9"},{"url":"https://git.kernel.org/stable/c/957e8be112636d9bc692917286e81e54bd87decc"},{"url":"https://git.kernel.org/stable/c/1d7def97e7eb65865ccc01bbdf4eb9e6bbe8a5b5"},{"url":"https://git.kernel.org/stable/c/748ebd8e61d0bc182c331b8df3887af7285c8a8f"},{"url":"https://git.kernel.org/stable/c/e791bf216c9e236b34dabf514ec0ede140cca719"},{"url":"https://git.kernel.org/stable/c/7ca84f6a22d50bf8b31efe9eb05f9859947266d7"},{"url":"https://git.kernel.org/stable/c/2c95c8f0959d0a72575eabf2ff888f47ed6d8b77"},{"url":"https://git.kernel.org/stable/c/f063a28002e3350088b4577c5640882bf4ea17ea"}],"title":"iio:
