https://notcve.org/view.php?id=CVE-2024-50007
In the Linux kernel, the following vulnerability has been resolved: ALSA: asihpi: Fix potential OOB array access ASIHPI driver stores some values in the static array upon a response from the driver, and its index depends on the firmware. We shouldn't trust it blindly. This patch adds a sanity check of the array index to fit in the array size. • https://git.kernel.org/stable/c/a6bdb691cf7b66dcd929de1a253c5c42edd2e522 https://git.kernel.org/stable/c/ce2953e44829ec54bcbb57e9d890fc8af0900c80 https://git.kernel.org/stable/c/219587bca2678e31700ef09ecec178ba1f735674 https://git.kernel.org/stable/c/36ee4021bcc37b834996e79740d095d6f8dd948f https://git.kernel.org/stable/c/e658227d9d4f4e122d81690fdbc0d438b10288f5 https://git.kernel.org/stable/c/7a55740996701f7b2bc46dc988b60ef2e416a747 https://git.kernel.org/stable/c/ad7248a5e92587b9266c62db8bcc4e58de53e372 https://git.kernel.org/stable/c/876d04bf5a8ac1d6af5afd258cd37ab83 •
CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2024-50006 – ext4: fix i_data_sem unlock order in ext4_ind_migrate()
https://notcve.org/view.php?id=CVE-2024-50006
In the Linux kernel, the following vulnerability has been resolved: ext4: fix i_data_sem unlock order in ext4_ind_migrate() Fuzzing reports a possible deadlock in jbd2_log_wait_commit. This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require synchronous updates because the file descriptor is opened with O_SYNC. This can lead to the jbd2_journal_stop() function calling jbd2_might_wait_for_commit(), potentially causing a deadlock if the EXT4_IOC_MIGRATE call races with a write(2) system call. This problem only arises when CONFIG_PROVE_LOCKING is enabled. In this case, the jbd2_might_wait_for_commit macro locks jbd2_handle in the jbd2_journal_stop function while i_data_sem is locked. This triggers lockdep because the jbd2_journal_start function might also lock the same jbd2_handle simultaneously. Found by Linux Verification Center (linuxtesting.org) with syzkaller.

https://notcve.org/view.php?id=CVE-2024-50003
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix system hang while resume with TBT monitor [Why] Connected with a Thunderbolt monitor and do the suspend and the system may hang while resume. The TBT monitor HPD will be triggered during the resume procedure and call the drm_client_modeset_probe() while struct drm_connector connector->dev->master is NULL. It will mess up the pipe topology after resume. [How] Skip the TBT monitor HPD during the resume procedure because we currently will probe the connectors after resume by default.

CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-50002 – static_call: Handle module init failure correctly in static_call_del_module()
https://notcve.org/view.php?id=CVE-2024-50002
In the Linux kernel, the following vulnerability has been resolved: static_call: Handle module init failure correctly in static_call_del_module() Module insertion invokes static_call_add_module() to initialize the static calls in a module. static_call_add_module() invokes __static_call_init(), which allocates a struct static_call_mod to either encapsulate the built-in static call sites of the associated key into it so further modules can be added or to append the module to the module chain. If that allocation fails the function returns with an error code and the module core invokes static_call_del_module() to clean up eventually added static_call_mod entries. This works correctly, when all keys used by the module were converted over to a module chain before the failure. If not then static_call_del_module() causes a #GP as it blindly assumes that key::mods points to a valid struct static_call_mod. The problem is that key::mods is not a individual struct member of struct static_call_key, it's part of a union to save space: union { /* bit 0: 0 = mods, 1 = sites */ unsigned long type; struct static_call_mod *mods; struct static_call_site *sites; }; key::sites is a pointer to the list of built-in usage sites of the static call. The type of the pointer is differentiated by bit 0. A mods pointer has the bit clear, the sites pointer has the bit set. As static_call_del_module() blidly assumes that the pointer is a valid static_call_mod type, it fails to check for this failure case and dereferences the pointer to the list of built-in call sites, which is obviously bogus. Cure it by checking whether the key has a sites or a mods pointer. If it's a sites pointer then the key is not to be touched. As the sites are walked in the same order as in __static_call_init() the site walk can be terminated because all subsequent sites have not been touched by the init code due to the error exit. If it was converted before the allocation fail, then the inner loop which searches for a module match will find nothing. A fail in the second allocation in __static_call_init() is harmless and does not require special treatment. • https://git.kernel.org/stable/c/9183c3f9ed710a8edf1a61e8a96d497258d26e08 https://git.kernel.org/stable/c/ed4c8ce0f307f2ab8778aeb40a8866d171e8f128 https://git.kernel.org/stable/c/b566c7d8a2de403ccc9d8a06195e19bbb386d0e4 https://git.kernel.org/stable/c/c0abbbe8c98c077292221ec7e2baa667c9f0974c https://git.kernel.org/stable/c/2b494471797bff3d257e99dc0a7abb0c5ff3b4cd https://git.kernel.org/stable/c/9c48c2b53191bf991361998f5bb97b8f2fc5a89c https://git.kernel.org/stable/c/4b30051c4864234ec57290c3d142db7c88f10d8a •
