However, on 32-bit arches, the roundup code itself\ncan overflow by doing a 32-bit left-shift of an unsigned long value,\nwhich is undefined behaviour, so it is not guaranteed to truncate\nneatly. This was triggered by syzbot on the DEVMAP_HASH type, which\ncontains the same check, copied from the hashtab code. So apply the same\nfix to hashtab, by moving the overflow check to before the roundup."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["kernel/bpf/hashtab.c"],"versions":[{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"33ec04cadb77605b71d9298311919303d390c4d5","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"92c81fbb3ed2e0dfc33a4183a67135e1ab566ace","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"64f00b4df0597590b199b62a37a165473bf658a6","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"3b08cfc65f07b1132c1979d73f014ae6e04de55d","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"a83fdaeaea3677b83a53f72ace2d73a19bcd6d93","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"8435f0961bf3dc65e204094349bd9aeaac1f8868","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"d817f0d34d927f2deb17dadbfe212c9a6a32ac3e","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"a6fa75b5096c0f9826a4fabe22d907b0a5bb1016","status":"affected","versionType":"git"},{"version":"daaf427c6ab392bedcd018e326b2ffa1e1110cd6","lessThan":"6787d916c2cf9850c97a0a3f73e08c43e7d973b1","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["kernel/bpf/hashtab.c"],"versions":[{"version":"3.19","status":"affected"},{"version":"0","lessThan":"3.19","status":"unaffected","versionType":"semver"},{"version":"4.19.311","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.273","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.214","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.153","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.83","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.23","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.11","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8.2","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","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":"3.19","versionEndExcluding":"4.19.311"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.4.273"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.10.214"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"5.15.153"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.1.83"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.6.23"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.7.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.8.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.19","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/33ec04cadb77605b71d9298311919303d390c4d5"},{"url":"https://git.kernel.org/stable/c/92c81fbb3ed2e0dfc33a4183a67135e1ab566ace"},{"url":"https://git.kernel.org/stable/c/64f00b4df0597590b199b62a37a165473bf658a6"},{"url":"https://git.kernel.org/stable/c/3b08cfc65f07b1132c1979d73f014ae6e04de55d"},{"url":"https://git.kernel.org/stable/c/a83fdaeaea3677b83a53f72ace2d73a19bcd6d93"},{"url":"https://git.kernel.org/stable/c/8435f0961bf3dc65e204094349bd9aeaac1f8868"},{"url":"https://git.kernel.org/stable/c/d817f0d34d927f2deb17dadbfe212c9a6a32ac3e"},{"url":"https://git.kernel.org/stable/c/a6fa75b5096c0f9826a4fabe22d907b0a5bb1016"},{"url":"https://git.kernel.org/stable/c/6787d916c2cf9850c97a0a3f73e08c43e7d973b1"}],"title":"bpf:
