https://notcve.org/view.php?id=CVE-2024-41025
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. Free the memory when it is not needed. • https://git.kernel.org/stable/c/0871561055e666da421d779397efcc1e5e964cab https://git.kernel.org/stable/c/8b8b82dcf393ceaca8c88939338fd4c30b5b11b2 https://git.kernel.org/stable/c/dbf4c31c9b039fd9734da156036492a2a7f78f64 https://git.kernel.org/stable/c/ad0bd973a033003ca578c42a760d1dc77aeea15e •

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 •

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-41021 – s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception()
https://notcve.org/view.php?id=CVE-2024-41021
In the Linux kernel, the following vulnerability has been resolved: s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception() There is no support for HWPOISON, MEMORY_FAILURE, or ARCH_HAS_COPY_MC on s390. Therefore we do not expect to see VM_FAULT_HWPOISON in do_exception(). However, since commit af19487f00f3 ("mm: make PTE_MARKER_SWAPIN_ERROR more general"), it is possible to see VM_FAULT_HWPOISON in combination with PTE_MARKER_POISONED, even on architectures that do not support HWPOISON otherwise. In this case, we will end up on the BUG() in do_exception(). Fix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar to x86 when MEMORY_FAILURE is not configured. Also print unexpected fault flags, for easier debugging. Note that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot support swap entries on other levels than PTE level. • https://git.kernel.org/stable/c/af19487f00f34ff8643921d7909dbb3fedc7e329 https://git.kernel.org/stable/c/73a9260b7366d2906ec011e100319359fe2277d0 https://git.kernel.org/stable/c/9e13767ccefdc4f8aa92514b592b60f6b54882ff https://git.kernel.org/stable/c/a3aefb871222a9880602d1a44a558177b4143e3b https://git.kernel.org/stable/c/df39038cd89525d465c2c8827eb64116873f141a •
