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 inodes.

https://notcve.org/view.php?id=CVE-2022-48627
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 deterministic. Fix this problem by using replacing the scr_memcpyw with scr_memmovew. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vt: corrige la superposición de memoria al eliminar caracteres en el búfer. Se produce una copia de memoria superpuesta al eliminar una línea larga. • https://git.kernel.org/stable/c/81732c3b2fede049a692e58a7ceabb6d18ffb18c https://git.kernel.org/stable/c/c8686c014b5e872ba7e334f33ca553f14446fc29 https://git.kernel.org/stable/c/815be99d934e3292906536275f2b8d5131cdf52c https://git.kernel.org/stable/c/bfee93c9a6c395f9aa62268f1cedf64999844926 https://git.kernel.org/stable/c/57964a5710252bc82fe22d9fa98c180c58c20244 https://git.kernel.org/stable/c/14d2cc21ca622310babf373e3a8f0b40acfe8265 https://git.kernel.org/stable/c/39cdb68c64d84e71a4a717000b6e5de208ee60cc https://lists.debian.org/debian-lts-announce/2024/06/ • CWE-1260: Improper Handling of Overlap Between Protected Memory Ranges •
