Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fixed an out-of-bounds access in rpage. When PAGESIZE is 64K, if logreadrst calls readlogpage for the first time, the size of buffer will be equal to DefaultLogPageSize4K. However, for buffer operations like memcpy, if...

CVE-2022-50869

The connected material confirms a Linux kernel issue in fs/ntfs3 causing slab-out-of-bounds when PAGE_SIZE is 64K. The root cause is a mismatch where read_log_page/log_read_rst may copy a 4K DefaultLogPageSize buffer into a larger destination (64K page), risking out-of-bounds access. The remediat...
