In the Linux kernel, the following vulnerability has been resolved: ASoC: ops: Fix bounds check for _sx controls For _sx controls the semantics of the max field is not the usual one, max is the number of steps rather than the maximum value. This means that our check in snd_soc_put_volsw_sx() needs to just check against the maximum value. • https://git.kernel.org/stable/c/9e5c40b5706d8aae2cf70bd7e01f0b4575a642d0 https://git.kernel.org/stable/c/4977491e4b3aad8567f57e2a9992d251410c1db3 https://git.kernel.org/stable/c/9a12fcbf3c622f9bf6b110a873d62b0cba93972e https://git.kernel.org/stable/c/c33402b056de61104b6146dedbe138ca8d7ec62b https://git.kernel.org/stable/c/038f8b7caa74d29e020949a43ca368c93f6b29b9 https://git.kernel.org/stable/c/e8e07c5e25a29e2a6f119fd947f55d7a55eb8a13 https://git.kernel.org/stable/c/4f1e50d6a9cf9c1b8c859d449b5031cacfa8404e https://git.kernel.org/stable/c/ef6cd9eeb38062a145802b7b56be7ae10 •

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix PCI device refcount leak in dmar_dev_scope_init() for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the error path to avoid reference count leak. • https://git.kernel.org/stable/c/2e45528930388658603ea24d49cf52867b928d3e https://git.kernel.org/stable/c/d47bc9d7bcdbb9adc9703513d964b514fee5b0bf https://git.kernel.org/stable/c/71c4a621985fc051ab86d3a86c749069a993fcb2 https://git.kernel.org/stable/c/876d7bfb89273997056220029ff12b1c2cc4691d https://git.kernel.org/stable/c/cbdd83bd2fd67142b03ce9dbdd1eab322ff7321f https://git.kernel.org/stable/c/a5c65cd56aed027f8a97fda8b691caaeb66d115e https://git.kernel.org/stable/c/bdb613ef179ad4bb9d56a2533e9b30e434f1dfb7 https://git.kernel.org/stable/c/2a8f7b90681472948de172dbbf5a54cd3 •

https://notcve.org/view.php?id=CVE-2022-48997
In the Linux kernel, the following vulnerability has been resolved: char: tpm: Protect tpm_pm_suspend with locks Currently tpm transactions are executed unconditionally in tpm_pm_suspend() function, which may lead to races with other tpm accessors in the system. Specifically, the hw_random tpm driver makes use of tpm_get_random(), and this function is called in a loop from a kthread, which means it's not frozen alongside userspace, and so can race with the work done during system suspend: tpm tpm0: tpm_transmit: tpm_recv: error -52 tpm tpm0: invalid TPM_STS.x 0xff, dumping stack for forensics CPU: 0 PID: 1 Comm: init Not tainted 6.1.0-rc5+ #135 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.0-20220807_005459-localhost 04/01/2014 Call Trace: tpm_tis_status.cold+0x19/0x20 tpm_transmit+0x13b/0x390 tpm_transmit_cmd+0x20/0x80 tpm1_pm_suspend+0xa6/0x110 tpm_pm_suspend+0x53/0x80 __pnp_bus_suspend+0x35/0xe0 __device_suspend+0x10f/0x350 Fix this by calling tpm_try_get_ops(), which itself is a wrapper around tpm_chip_start(), but takes the appropriate mutex.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2022-48994 – ALSA: seq: Fix function prototype mismatch in snd_seq_expand_var_event
https://notcve.org/view.php?id=CVE-2022-48994
In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix function prototype mismatch in snd_seq_expand_var_event With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. seq_copy_in_user() and seq_copy_in_kernel() did not have prototypes matching snd_seq_dump_func_t. Adjust this and remove the casts. There are not resulting binary output differences. This was found as a result of Clang's new -Wcast-function-type-strict flag, which is more sensitive than the simpler -Wcast-function-type, which only checks for type width mismatches. • https://git.kernel.org/stable/c/b38486e82ecb9f3046e0184205f6b61408fc40c9 https://git.kernel.org/stable/c/e385360705a0b346bdb57ce938249175d0613b8a https://git.kernel.org/stable/c/2f46e95bf344abc4e74f8158901d32a869e0adb6 https://git.kernel.org/stable/c/63badfed200219ca656968725f1a43df293ac936 https://git.kernel.org/stable/c/15c42ab8d43acb73e2eba361ad05822c0af0ecfa https://git.kernel.org/stable/c/fccd454129f6a0739651f7f58307cdb631fd6e89 https://git.kernel.org/stable/c/13ee8fb5410b740c8dd2867d3557c7662f7dda2d https://git.kernel.org/stable/c/05530ef7cf7c7d700f6753f058999b1b5 •
