"The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-56548 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: hfsplus: don't query the device
    logical block size multiple times Devices block sizes May change. One of these cases is a loop device by
    using ioctl LOOP_SET_BLOCK_SIZE. While this May cause other issues like IO being rejected, in the case of
    hfsplus, it will allocate a block by using that size and potentially write out-of-bounds when
    hfsplus_read_wrapper calls hfsplus_submit_bio and the latter function reads a different io_size. Using a
    new min_io_size initally set to sb_min_blocksize works for the purposes of the original fix, since it will
    be set to the max between HFSPLUS_SECTOR_SIZE and the first seen logical block size. We still use the max
    between HFSPLUS_SECTOR_SIZE and min_io_size in case the latter is not initialized. Tested by mounting an
    hfsplus filesystem with loop block sizes 512, 1024 and 4096. The produced KASAN report before the fix
    looks like this: [ 419.944641] ================================================================== [
