In the Linux kernel, the following vulnerability has been resolved: x86/alternatives: Disable KASAN in apply_alternatives() Fei has reported that KASAN triggers during apply_alternatives() on a 5-level paging machine: BUG: KASAN: out-of-bounds in rcu_is_watching() Read of size 4 at addr ff110003ee6419a0 by task swapper/0/0 ... __asan_load4() rcu_is_watching() trace_hardirqs_on() text_poke_early() apply_alternatives() ... On machines with 5-level paging, cpu_feature_enabled(X86_FEATURE_LA57) gets patched. It includes KASAN code, where KASAN_SHADOW_START depends on __VIRTUAL_MASK_SHIFT, which is defined with cpu_feature_enabled(). KASAN gets confused when apply_alternatives() patches the KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START static, by replacing __VIRTUAL_MASK_SHIFT with 56, works around the issue. Fix it for real by disabling KASAN while the kernel is patching alternatives.

    2024-06-06: CVE-2023-52477 was added to this advisory.

    A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can     lead to a use-after-free vulnerability and crash. (CVE-2023-3397)

    An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access     to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES     emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege     escalation). This depends on a race condition through which userspace can replace an instruction before     the #VC handler reads it. (CVE-2023-46813)

    In the Linux kernel, the following vulnerability has been resolved:

    usb: hub: Guard against accesses to uninitialized BOS descriptors (CVE-2023-52477)

    In the Linux kernel, the following vulnerability has been resolved:

    x86/alternatives: Disable KASAN in apply_alternatives() (CVE-2023-52504)

    A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation.

    If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it     can increment or write to memory locations outside of the allocated buffer.

    We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)
