https://notcve.org/view.php?id=CVE-2024-40939
In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: Fix tainted pointer delete is case of region creation fail In case of region creation fail in ipc_devlink_create_region(), previously created regions delete process starts from tainted pointer which actually holds error code value. Fix this bug by decreasing region index before delete.

https://notcve.org/view.php?id=CVE-2024-40938
In the Linux kernel, the following vulnerability has been resolved: landlock: Fix d_parent walk The WARN_ON_ONCE() in collect_domain_accesses() can be triggered when trying to link a root mount point. This cannot work in practice because this directory is mounted, but the VFS check is done after the call to security_path_link(). Do not use source directory's d_parent when the source directory is the mount point.

In the Linux kernel, the following vulnerability has been resolved: gve: Clear napi->skb before dev_kfree_skb_any() gve_rx_free_skb incorrectly leaves napi->skb referencing an skb after it is freed with dev_kfree_skb_any(). This can result in a subsequent call to napi_get_frags returning a dangling pointer. Fix this by clearing napi->skb before the skb is freed. • https://git.kernel.org/stable/c/9b8dd5e5ea48bbb7532d20c4093a79d8283e4029 https://git.kernel.org/stable/c/75afd8724739ee5ed8165acde5f6ac3988b485cc https://git.kernel.org/stable/c/d221284991118c0ab16480b53baecd857c0bc442 https://git.kernel.org/stable/c/2ce5341c36993b776012601921d7688693f8c037 https://git.kernel.org/stable/c/a68184d5b420ea4fc7e6b7ceb52bbc66f90d3c50 https://git.kernel.org/stable/c/6f4d93b78ade0a4c2cafd587f7b429ce95abb02e •

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-40935 – cachefiles: flush all requests after setting CACHEFILES_DEAD
https://notcve.org/view.php?id=CVE-2024-40935
In the Linux kernel, the following vulnerability has been resolved: cachefiles: flush all requests after setting CACHEFILES_DEAD In ondemand mode, when the daemon is processing an open request, if the kernel flags the cache as CACHEFILES_DEAD, the cachefiles_daemon_write() will always return -EIO, so the daemon can't pass the copen to the kernel. Then the kernel process that is waiting for the copen triggers a hung_task. Since the DEAD state is irreversible, it can only be exited by closing /dev/cachefiles. Therefore, after calling cachefiles_io_error() to mark the cache as CACHEFILES_DEAD, if in ondemand mode, flush all requests to avoid the above hungtask. We may still be able to read some of the cached data before closing the fd of /dev/cachefiles. Note that this relies on the patch that adds reference counting to the req, otherwise it may UAF. • https://git.kernel.org/stable/c/c8383054506c77b814489c09877b5db83fd4abf2 https://git.kernel.org/stable/c/320ba9cbca78be79c912143bbba1d1b35ca55cf0 https://git.kernel.org/stable/c/3bf0b8030296e9ee60d3d4c15849ad9ac0b47081 https://git.kernel.org/stable/c/e73fac95084839c5178d97e81c6a2051251bdc00 https://git.kernel.org/stable/c/85e833cd7243bda7285492b0653c3abb1e2e757b •
