https://notcve.org/view.php?id=CVE-2022-48704
In the Linux kernel, the following vulnerability has been resolved: drm/radeon: add a force flush to delay work when radeon Although radeon card fence and wait for gpu to finish processing current batch rings, there is still a corner case that radeon lockup work queue may not be fully flushed, and meanwhile the radeon_suspend_kms() function has called pci_set_power_state() to put device in D3hot state. Per PCI spec rev 4.0 on 5.3.1.4.1 D3hot State. > Configuration and Message requests are the only TLPs accepted by a Function in > the D3hot state. All other received Requests must be handled as Unsupported Requests, > and all received Completions may optionally be handled as Unexpected Completions.

In the Linux kernel, the following vulnerability has been resolved: thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault.

https://notcve.org/view.php?id=CVE-2022-48702
In the Linux kernel, the following vulnerability has been resolved: ALSA: emu10k1: Fix out of bounds access in snd_emu10k1_pcm_channel_alloc() The voice allocator sometimes begins allocating from near the end of the array and then wraps around, however snd_emu10k1_pcm_channel_alloc() accesses the newly allocated voices as if it never wrapped around. This results in out of bounds access if the first voice has a high enough index so that first_voice + requested_voice_count > NUM_G (64). The more voices are requested, the more likely it is for this to occur. This was initially discovered using PipeWire, however it can be reproduced by calling aplay multiple times with 16 channels: aplay -r 48000 -D plughw:CARD=Live,DEV=3 -c 16 /dev/zero UBSAN: array-index-out-of-bounds in sound/pci/emu10k1/emupcm.c:127:40 index 65 is out of range for type 'snd_emu10k1_voice [64]' CPU: 1 PID: 31977 Comm: aplay Tainted: G W IOE 6.0.0-rc2-emu10k1+ #7 Hardware name: ASUSTEK COMPUTER INC P5W DH Deluxe/P5W DH Deluxe, BIOS 3002 07/22/2010 Call Trace: <TASK> dump_stack_lvl+0x49/0x63 dump_stack+0x10/0x16 ubsan_epilogue+0x9/0x3f __ubsan_handle_out_of_bounds.cold+0x44/0x49 snd_emu10k1_playback_hw_params+0x3bc/0x420 [snd_emu10k1] snd_pcm_hw_params+0x29f/0x600 [snd_pcm] snd_pcm_common_ioctl+0x188/0x1410 [snd_pcm] ? exit_to_user_mode_prepare+0x35/0x170 ? do_syscall_64+0x69/0x90 ? syscall_exit_to_user_mode+0x26/0x50 ? do_syscall_64+0x69/0x90 ? • https://git.kernel.org/stable/c/637c5310acb48fffcc5657568db3f3e9bc719bfa https://git.kernel.org/stable/c/6b0e260ac3cf289e38446552461caa65e6dab275 https://git.kernel.org/stable/c/88aac6684cf8bc885cca15463cb4407e91f28ff7 https://git.kernel.org/stable/c/45321a7d02b7cf9b3f97e3987fc1e4d649b82da2 https://git.kernel.org/stable/c/39a90720f3abe96625d1224e7a7463410875de4c https://git.kernel.org/stable/c/45814a53514e10a8014906c882e0d0d38df39cc1 https://git.kernel.org/stable/c/4204a01ffce97cae1d59edc5848f02be5b2b9178 https://git.kernel.org/stable/c/d29f59051d3a07b81281b2df2b8c9dfe4 •
