29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_hd_modes In nv17_tv_get_hd_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). The same applies to drm_cvt_mode(). Add a check to avoid null pointer dereference.

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: cxl/region: Avoid null pointer dereference in region lookup cxl_dpa_to_region() looks up a region based on a memdev and DPA. It wrongly assumes an endpoint found mapping the DPA is also of a fully assembled region. When not true it leads to a null pointer dereference looking up the region name.

CVE-2024-41082 – nvme-fabrics: use reserved tag for reg read/write command

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: nvme-fabrics: use reserved tag for reg read/write command In some scenarios, if too many commands are issued by nvme command in the same time by user tasks, this may exhaust all tags of admin_q. If a reset (nvme reset or IO timeout) occurs before these commands finish, reconnect routine may fail to update nvme regs due to insufficient tags, which will cause kernel hang forever.

CVE-2024-41080 – io_uring: fix possible deadlock in io_register_iowq_max_workers()

29 Jul 2024 — In the Linux kernel, the following vulnerability has been resolved: io_uring: fix possible deadlock in io_register_iowq_max_workers() The io_register_iowq_max_workers() function calls io_put_sq_data(), which acquires the sqd->lock without releasing the uring_lock. Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lock before acquiring sqd->lock"), this can lead to a potential deadlock situation. To resolve this issue, the uring_lock is released before calling io_put_sq_data(), and then it is re... • https://git.kernel.org/stable/c/b17397a0a5c56e111f61cb5b77d162664dc00de9 •
