Pre-existing allocations are already counted against the\nrequest through mas_node_count_gfp(), but the allocations will not happen\nif the MA_STATE_PREALLOC flag is set.  This flag is meant to avoid\nre-allocating in bulk allocation mode, and to detect issues with\npreallocation calculations.\n\nThe MA_STATE_PREALLOC flag should also always be set on zero allocations\nso that detection of underflow allocations will print a WARN_ON() during\nconsumption.\n\nUser visible effect of this flaw is a WARN_ON() followed by a null pointer\ndereference when subsequent requests for larger number of nodes is\nignored, such as the vma merge retry in mmap_region() caused by drivers\naltering the vma flags (which happens in v6.6, at least)"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["lib/maple_tree.c"],"versions":[{"version":"54a611b605901c7d5d05b6b8f5d04a6ceb0962aa","lessThan":"d69cd64bd5af41c6fd409313504089970edaf02f","status":"affected","versionType":"git"},{"version":"54a611b605901c7d5d05b6b8f5d04a6ceb0962aa","lessThan":"e63032e66bca1d06e600033f3369ba3db3af0870","status":"affected","versionType":"git"},{"version":"54a611b605901c7d5d05b6b8f5d04a6ceb0962aa","lessThan":"cf95f8426f889949b738f51ffcd72884411f3a6a","status":"affected","versionType":"git"},{"version":"54a611b605901c7d5d05b6b8f5d04a6ceb0962aa","lessThan":"9e32f4700867abbd5d19abfcf698dbd0d2ce36a4","status":"affected","versionType":"git"},{"version":"54a611b605901c7d5d05b6b8f5d04a6ceb0962aa","lessThan":"fba46a5d83ca8decb338722fb4899026d8d9ead2","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["lib/maple_tree.c"],"versions":[{"version":"6.1","status":"affected"},{"version":"0","lessThan":"6.1","status":"unaffected","versionType":"semver"},{"version":"6.1.146","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.99","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.36","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.15.5","lessThanOrEqual":"6.15.*","status":"unaffected","versionType":"semver"},{"version":"6.16","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":"6.1","versionEndExcluding":"6.1.146"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.6.99"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.12.36"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.15.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.16"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d69cd64bd5af41c6fd409313504089970edaf02f"},{"url":"https://git.kernel.org/stable/c/e63032e66bca1d06e600033f3369ba3db3af0870"},{"url":"https://git.kernel.org/stable/c/cf95f8426f889949b738f51ffcd72884411f3a6a"},{"url":"https://git.kernel.org/stable/c/9e32f4700867abbd5d19abfcf698dbd0d2ce36a4"},{"url":"https://git.kernel.org/stable/c/fba46a5d83ca8decb338722fb4899026d8d9ead2"}],"title":"maple_tree:
