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 •

In the Linux kernel, the following vulnerability has been resolved: filelock: Fix fcntl/close race recovery compat path When I wrote commit 3cad1bc01041 ("filelock: Remove locks reliably when fcntl/close race is detected"), I missed that there are two copies of the code I was patching: The normal version, and the version for 64-bit offsets on 32-bit kernels. Thanks to Greg KH for stumbling over this while doing the stable backport... Apply exactly the same fix to the compat path for 32-bit kernels. An LSM can prevent the fcntl/close race cleanup path in fcntl_setlk() from working, leading to use-after-free read in lock_get_status() when reading /proc/locks. • https://git.kernel.org/stable/c/c293621bbf678a3d85e3ed721c3921c8a670610d https://git.kernel.org/stable/c/a561145f3ae973ebf3e0aee41624e92a6c5cb38d https://git.kernel.org/stable/c/4c43ad4ab41602201d34c66ac62130fe339d686f https://git.kernel.org/stable/c/911cc83e56a2de5a40758766c6a70d6998248860 https://git.kernel.org/stable/c/53e21cfa68a7d12de378b7116c75571f73e0dfa2 https://git.kernel.org/stable/c/f4d0775c6e2f1340ca0725f0337de149aaa989ca https://git.kernel.org/stable/c/73ae349534ebc377328e7d21891e589626c6e82c https://git.kernel.org/stable/c/5b0af8e4c70e4b884bb94ff5f0cd49ecf • CWE-667: Improper Locking •
