CVE-2023-52762 – virtio-blk: fix implicit overflow on virtio_max_dma_size
https://notcve.org/view.php?id=CVE-2023-52762
21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: virtio-blk: fix implicit overflow on virtio_max_dma_size The following codes have an implicit conversion from size_t to u32: (u32)max_size = (size_t)virtio_max_dma_size(vdev); This may lead overflow, Ex (size_t)4G -> (u32)0. Once virtio_max_dma_size() has a larger size than U32_MAX, use U32_MAX instead. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: virtio-blk: corrige el desbordamiento implícito en virtio_max_dma_size.

CVE-2023-52761 – riscv: VMAP_STACK overflow detection thread-safe
https://notcve.org/view.php?id=CVE-2023-52761
21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: riscv: VMAP_STACK overflow detection thread-safe commit 31da94c25aea ("riscv: add VMAP_STACK overflow detection") added support for CONFIG_VMAP_STACK. If overflow is detected, CPU switches to `shadow_stack` temporarily before switching finally to per-cpu `overflow_stack`. If two CPUs/harts are racing and end up in over flowing kernel stack, one or both will end up corrupting each other state because `shadow_stack` is not per-cpu.

CVE-2023-52760 – gfs2: Fix slab-use-after-free in gfs2_qd_dealloc

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix slab-use-after-free in gfs2_qd_dealloc In gfs2_put_super(), whether withdrawn or not, the quota should be cleaned up by gfs2_quota_cleanup(). Otherwise, struct gfs2_sbd will be freed before gfs2_qd_dealloc (rcu callback) has run for all gfs2_quota_data objects, resulting in use-after-free. Also, gfs2_destroy_threads() and gfs2_quota_cleanup() is already called by gfs2_make_fs_ro(), so in gfs2_put_super(), after calling gfs2_make_f... • https://git.kernel.org/stable/c/7ad4e0a4f61c57c3ca291ee010a9d677d0199fba • CWE-416: Use After Free •

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential deadlock when releasing mids All release_mid() callers seem to hold a reference of @mid so there is no need to call kref_put(&mid->refcount, __release_mid) under @server->mid_lock spinlock. If they don't, then an use-after-free bug would have occurred anyways. By getting rid of such spinlock also fixes a potential deadlock as shown below CPU 0 CPU 1 -----------------------------------------------------------------... • https://git.kernel.org/stable/c/9eb44db68c5b7f5aa22b8fc7de74a3e2e08d1f29 • CWE-833: Deadlock •

21 May 2024 — In the Linux kernel, the following vulnerability has been resolved: media: imon: fix access to invalid resource for the second interface imon driver probes two USB interfaces, and at the probe of the second interface, the driver assumes blindly that the first interface got bound with the same imon driver. It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver ac... • https://git.kernel.org/stable/c/0f5068519f89d928d6c51100e4b274479123829f •
