https://notcve.org/view.php?id=CVE-2023-53097
02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: powerpc/iommu: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once. In the Linux kernel, the following vulnerability has been resolved: powerpc/iommu: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the ... • https://git.kernel.org/stable/c/e3a62a35f903fd8be5b44542fe3901ec45f16757 •

CVE-2023-53093 – tracing: Do not let histogram values have some modifiers
https://notcve.org/view.php?id=CVE-2023-53093
02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: tracing: Do not let histogram values have some modifiers Histogram values can not be strings, stacktraces, graphs, symbols, syscalls, or grouped in buckets or log. Give an error if a value is set to do so. Note, the histogram code was not prepared to handle these modifiers for histograms and caused a bug.

CVE-2023-53091 – ext4: update s_journal_inum if it changes after journal replay
https://notcve.org/view.php?id=CVE-2023-53091
02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: ext4: update s_journal_inum if it changes after journal replay When mounting a crafted ext4 image, s_journal_inum may change after journal replay, which is obviously unreasonable because we have successfully loaded and replayed the journal through the old s_journal_inum. And the new s_journal_inum bypasses some of the checks in ext4_get_journal(), which may trigger a null pointer dereference problem. So if s_journal_inum changes after the j... • https://git.kernel.org/stable/c/499fef2030fb754c68b1c7cb3a799a3bc1d0d925 •
