[PATCH OLK-6.6] gpio: xilinx: Convert gpio_lock to raw spinlock

From: Sean Anderson <sean.anderson(a)linux.dev> stable inclusion from stable-v6.6.74 commit b0111650ee596219bb5defa0ce1a1308e6e77ccf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBL2TF CVE: CVE-2025-21684 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 9860370c2172704b6b4f0075a0c2a29fd84af96a upstream. irq_chip functions may be called in raw spinlock context.

[PATCH OLK-5.10] ALSA: seq: oss: Fix races at processing SysEx messages
by Gu Bowen 11 Feb '25

11 Feb '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.70 commit d2392b79d8af3714ea8878b71c66dc49d3110f44 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID2T CVE: CVE-2024-57893 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 0179488ca992d79908b8e26b9213f1554fc5bacc upstream. OSS sequencer handles the SysEx messages split in 6 bytes packets, and ALSA sequencer OSS layer tries to combine those. It stores the data in the internal buffer and this access is racy as of now, which may lead to the out-of-bounds access. As a temporary band-aid fix, introduce a mutex for serializing the process of the SysEx message packets.
