https://notcve.org/view.php?id=CVE-2024-45024
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix hugetlb vs. core-mm PT locking We recently made GUP's common page table walking code to also walk hugetlb VMAs without most hugetlb special-casing, preparing for the future of having less hugetlb-specific page table walking code in the codebase. Turns out that we missed one page table locking detail: page table locking for hugetlb folios that are not mapped using a single PMD/PUD. Assume we have hugetlb folio that spans multiple PTEs (e.g., 64 KiB hugetlb folios on arm64 with 4 KiB base page size). • https://git.kernel.org/stable/c/9cb28da54643ad464c47585cd5866c30b0218e67 https://git.kernel.org/stable/c/7300dadba49e531af2d890ae4e34c9b115384a62 https://git.kernel.org/stable/c/5f75cfbd6bb02295ddaed48adf667b6c828ce07b •

In the Linux kernel, the following vulnerability has been resolved: md/raid1: Fix data corruption for degraded array with slow disk read_balance() will avoid reading from slow disks as much as possible, however, if valid data only lands in slow disks, and a new normal disk is still in recovery, unrecovered data can be read: raid1_read_request read_balance raid1_should_read_first -> return false choose_best_rdev -> normal disk is not recovered, return -1 choose_bb_rdev -> missing the checking of recovery, return the normal disk -> read unrecovered data Root cause is that the checking of recovery is missing in choose_bb_rdev(). • https://git.kernel.org/stable/c/9f3ced792203891b8fa39afa37908eba843fcfac https://git.kernel.org/stable/c/2febf5fdbf5d9a52ddc3e986971c8609b1582d67 https://git.kernel.org/stable/c/c916ca35308d3187c9928664f9be249b22a3a701 •
