the Linux kernel, the following vulnerability has been resolved:\n\nfs/proc: fix softlockup in __read_vmcore (part 2)\n\nSince commit 5cbcb62dddf5 (\"fs/proc: fix softlockup in __read_vmcore\") the\nnumber of softlockups in __read_vmcore at kdump time have gone down, but\nthey still happen sometimes.\n\nIn a memory constrained environment like the kdump image, a softlockup is\nnot just a harmless message, but it can interfere with things like RCU\nfreeing memory, causing the crashdump to get stuck.\n\nThe second loop in __read_vmcore has a lot more opportunities for natural\nsleep points, like scheduling out while waiting for a data write to\nhappen, but apparently that is not always enough.\n\nAdd a cond_resched() to the second loop in __read_vmcore to (hopefully)\nget rid of the softlockups."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/proc/vmcore.c"],"versions":[{"version":"803d5a33d5ffdc2d86dcc0cfa01655a330612cdb","lessThan":"84c4ed15626574c9ac6c1039ba9c137a77bcc7f2","status":"affected","versionType":"git"},{"version":"70c1835e776c8447c1aca87ddb38cfe764fe756a","lessThan":"80da29deb88a3a907441fc35bb7bac309f31e713","status":"affected","versionType":"git"},{"version":"e1b160a50c756e0efbea290b9bf5117cb80e8c4b","lessThan":"649b266606bc413407ce315f710c8ce8a88ee30a","status":"affected","versionType":"git"},{"version":"a373ad833a6bfe4bc6cedcf7e56a99cc6fd9a193","lessThan":"65c367bd9d4f43513c7f837df5753bea9561b836","status":"affected","versionType":"git"},{"version":"518fbd644dabb6aedbdd4939c6c9cc1bf651459f","lessThan":"a5a2ee8144c3897d37403a69118c3e3dc5713958","status":"affected","versionType":"git"},{"version":"5cbcb62dddf5346077feb82b7b0c9254222d3445","lessThan":"80828540dad0757b6337c6561d49c81038f38d87","status":"affected","versionType":"git"},{"version":"5cbcb62dddf5346077feb82b7b0c9254222d3445","lessThan":"cbc5dde0a461240046e8a41c43d7c3b76d5db952","status":"affected","versionType":"git"},{"version":"7bdf1d550ddfcd9ab797087421f77b7aceddc8a7","status":"affected","versionType":"git"},{"version":"e8780e8a0e25dc4c3927f611ec8970d26c0c7369","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/proc/vmcore.c"],"versions":[{"version":"6.10","status":"affected"},{"version":"0","lessThan":"6.10","status":"unaffected","versionType":"semver"},{"version":"5.4.290","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.234","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.177","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.127","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.74","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.11","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13","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":"5.4.279","versionEndExcluding":"5.4.290"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10.221","versionEndExcluding":"5.10.234"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.15.162","versionEndExcluding":"5.15.177"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.95","versionEndExcluding":"6.1.127"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6.35","versionEndExcluding":"6.6.74"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"6.12.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"6.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19.317"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9.6"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/84c4ed15626574c9ac6c1039ba9c137a77bcc7f2"},{"url":"https://git.kernel.org/stable/c/80da29deb88a3a907441fc35bb7bac309f31e713"},{"url":"https://git.kernel.org/stable/c/649b266606bc413407ce315f710c8ce8a88ee30a"},{"url":"https://git.kernel.org/stable/c/65c367bd9d4f43513c7f837df5753bea9561b836"},{"url":"https://git.kernel.org/stable/c/a5a2ee8144c3897d37403a69118c3e3dc5713958"},{"url":"https://git.kernel.org/stable/c/80828540dad0757b6337c6561d49c81038f38d87"},{"url":"https://git.kernel.org/stable/c/cbc5dde0a461240046e8a41c43d7c3b76d5db952"}],"title":"fs/proc:
