From: Jann Horn <jannh(a)google.com> mainline inclusion from mainline-v6.10-rc2 commit 80e648042e512d5a767da251d44132553fe04ae0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC5K CVE: CVE-2025-21772 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Fix several issues in partition probing: - The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded. - If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory. - We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().

[PATCH OLK-6.6] ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> mainline inclusion from mainline-v6.14-rc1 commit 301c26a018acb94dd537a4418cefa0f654500c6f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED3 CVE: CVE-2024-58077 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.
