[PATCH OLK-6.6] soc: imx8m: Probe the SoC driver as platform driver
by Tirui Yin 21 Jan '25

21 Jan '25

From: Marek Vasut <marex(a)denx.de> stable inclusion from stable-v6.6.66 commit 2129f6faa5dfe8c6b87aad11720bf75edd77d3e4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIHOP CVE: CVE-2024-56787 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 9cc832d37799dbea950c4c8a34721b02b8b5a8ff ] With driver_async_probe=* on kernel command line, the following trace is produced because on i.MX8M Plus hardware because the soc-imx8m.c driver calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock driver is not yet probed. This was not detected during regular testing without driver_async_probe. Convert the SoC code to platform driver and instantiate a platform device in its current device_initcall() to probe the platform driver. Rework .soc_revision callback to always return valid error code and return SoC revision via parameter. This way, if anything in the .soc_revision callback return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get retried later.

[PATCH OLK-6.6] arm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRL
by Yuntao Liu 21 Jan '25

21 Jan '25

From: Mark Rutland <mark.rutland(a)arm.com> stable inclusion from stable-v6.6.66 commit 96035c0093db258975b8887676afe59a64c34a72 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIO47 CVE: CVE-2024-57874 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Currently tagged_addr_ctrl_set() doesn't initialize the temporary 'ctrl' variable, and a SETREGSET call with a length of zero will leave this uninitialized. Consequently tagged_addr_ctrl_set() will consume an arbitrary value, potentially leaking up to 64 bits of memory from the kernel stack. The read is limited to a specific slot on the stack, and the issue does not provide a write mechanism. As set_tagged_addr_ctrl() only accepts values where bits [63:4] zero and rejects other values, a partial SETREGSET attempt will randomly succeed or fail depending on the value of the uninitialized value, and the exposure is significantly limited. Fix this by initializing the temporary value before copying the regset from userspace, as for other regsets (e.g. NT_PRSTATUS, NT_PRFPREG, NT_ARM_SYSTEM_CALL). In the case of a zero-length write, the existing value of the tagged address ctrl will be retained. The NT_ARM_TAGGED_ADDR_CTRL regset is only visible in the user_aarch64_view used by a native AArch64 task to manipulate another native AArch64 task. As get_tagged_addr_ctrl() only returns an error value when called for a compat task, tagged_addr_ctrl_get() and tagged_addr_ctrl_set() should never observe an error value from get_tagged_addr_ctrl(). Add a WARN_ON_ONCE() to both to indicate that such an error would be unexpected, and error handlnig is not missing in either case.
