CVE-2024-57923
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
btrfs: zlib: fix avail_in bytes for s390 zlib HW compression path
Since the input data length passed to zlib_compress_folios() can be arbitrary, always setting strm.avail_in to a multiple of PAGE_SIZE may cause read-in bytes to exceed the input range. Currently this triggers an assert in btrfs_compress_folios() on the debug kernel (see below). Fix strm.avail_in calculation for S390 hardware acceleration path.
