CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-41027 – Fix userfaultfd_api to return EINVAL as expected
https://notcve.org/view.php?id=CVE-2024-41027
In the Linux kernel, the following vulnerability has been resolved: Fix userfaultfd_api to return EINVAL as expected Currently if we request a feature that is not set in the Kernel config we fail silently and return all the available features. However, the man page indicates we should return an EINVAL. We need to fix this issue since we can end up with a Kernel warning should a program request the feature UFFD_FEATURE_WP_UNPOPULATED on a kernel with the config not set with this feature.

In the Linux kernel, the following vulnerability has been resolved: mmc: davinci_mmc: Prevent transmitted data size from exceeding sgm's length No check is done on the size of the data to be transmiited. This causes a kernel panic when this size exceeds the sg_miter's length.

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Fix memory leak in audio daemon attach operation Audio PD daemon send the name as part of the init IOCTL call. This name needs to be copied to kernel for which memory is allocated. This memory is never freed which might result in memory leak.

https://notcve.org/view.php?id=CVE-2024-41024
In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Restrict untrusted app to attach to privileged PD Untrusted application with access to only non-secure fastrpc device node can attach to root_pd or static PDs if it can make the respective init request. This can cause problems as the untrusted application can send bad requests to root_pd or static PDs. Add changes to reject attach to privileged PDs if the request is being made using non-secure fastrpc device node. • https://git.kernel.org/stable/c/0871561055e666da421d779397efcc1e5e964cab https://git.kernel.org/stable/c/5e305b5986dc52122a9368a1461f0c13e1de3fd6 https://git.kernel.org/stable/c/ea13bd807f1cef1af375d999980a9b9794c789b6 https://git.kernel.org/stable/c/c69fd8afacebfdf2f8a1ee1ea7e0723786529874 https://git.kernel.org/stable/c/bab2f5e8fd5d2f759db26b78d9db57412888f187 https://git.kernel.org/stable/c/2eb973ee4770a26d9b5e292b58ad29822d321c7f •

The timer callback, dl_task_timer, is supposed to decrement the reference count upon expiration. However, if enqueue_task_dl() is called before the timer expires and cancels it, the reference count is not decremented, leading to the leak. This patch fixes the reference leak by ensuring the task_struct reference count is properly decremented when the timer is canceled. • https://git.kernel.org/stable/c/feff2e65efd8d84cf831668e182b2ce73c604bbb https://git.kernel.org/stable/c/f0e1c1d8ff908a39dd42e723d08f104505dfa601 https://git.kernel.org/stable/c/184c8ab5342450c4ae6fc5d937f9bb06c620dcf1 https://git.kernel.org/stable/c/7a54d31face626f62de415ebe77b43f76c3ffaf4 https://git.kernel.org/stable/c/b58652db66c910c2245f5bee7deca41c12d707b9 https://access.redhat.com/security/cve/CVE-2024-41023 https://bugzilla.redhat.com/show_bug.cgi?id=2300381 • CWE-401: Missing Release of Memory after Effective Lifetime •
