02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: ceph: drop messages from MDS when unmounting When unmounting all the dirty buffers will be flushed and after the last osd request is finished the last reference of the i_count will be released. Then it will flush the dirty cap/snap to MDSs, and the unmounting won't wait the possible acks, which will ihold the inodes when updating the metadata locally but makes no sense any more, of this. This will make the evict_inodes() to skip these inode... • https://git.kernel.org/stable/c/89744b64914426cbabceb3d8a149176b5dafdfb5 •
CVE-2022-48627 – vt: fix memory overlapping when deleting chars in the buffer

02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: vt: fix memory overlapping when deleting chars in the buffer A memory overlapping copy occurs when deleting a long line. This memory overlapping copy can cause data corruption when scr_memcpyw is optimized to memcpy because memcpy does not ensure its behavior if the destination buffer overlaps with the source buffer. The line buffer is not always broken, because the memcpy utilizes the hardware acceleration, whose result is not deterministi... • https://git.kernel.org/stable/c/81732c3b2fede049a692e58a7ceabb6d18ffb18c • CWE-1260: Improper Handling of Overlap Between Protected Memory Ranges •
