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 •

CVSS: 4.4EPSS: 0%CPEs: 6EXPL: 0CVE-2023-52498 – PM: sleep: Fix possible deadlocks in core system-wide PM code
https://notcve.org/view.php?id=CVE-2023-52498
In the Linux kernel, the following vulnerability has been resolved: PM: sleep: Fix possible deadlocks in core system-wide PM code It is reported that in low-memory situations the system-wide resume core code deadlocks, because async_schedule_dev() executes its argument function synchronously if it cannot allocate memory (and not only in that case) and that function attempts to acquire a mutex that is already held. Executing the argument function synchronously from within dpm_async_fn() may also be problematic for ordering reasons (it may cause a consumer device's resume callback to be invoked before a requisite supplier device's one, for example). Address this by changing the code in question to use async_schedule_dev_nocall() for scheduling the asynchronous execution of device suspend and resume functions and to directly run them synchronously if async_schedule_dev_nocall() returns false. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PM: suspensión: soluciona posibles bloqueos en el código PM de todo el sistema central. Se informa que en situaciones de poca memoria, el código central de reanudación de todo el sistema se bloquea porque async_schedule_dev() ejecuta su el argumento funciona sincrónicamente si no puede asignar memoria (y no solo en ese caso) y esa función intenta adquirir un mutex que ya está retenido. La ejecución de la función de argumento sincrónicamente desde dpm_async_fn() también puede ser problemática por razones de pedido (puede causar que la devolución de llamada de currículum de un dispositivo consumidor se invoque antes que la de un dispositivo proveedor requerido, por ejemplo). • https://git.kernel.org/stable/c/f46eb832389f162ad13cb780d0b8cde93641990d https://git.kernel.org/stable/c/a1d62c775b07213c73f81ae842424c74dd14b5f0 https://git.kernel.org/stable/c/e1c9d32c98309ae764893a481552d3f99d46cb34 https://git.kernel.org/stable/c/e681e29d1f59a04ef773296e4bebb17b1b79f8fe https://git.kernel.org/stable/c/9bd3dce27b01c51295b60e1433e1dadfb16649f7 https://git.kernel.org/stable/c/7839d0078e0d5e6cc2fa0b0dfbee71de74f1e557 https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://access.redhat.com/security/cve/CVE-2023 • CWE-833: Deadlock •
