    ACPI: CPPC: Use access_width over bit_width for system memory accesses

    In the Linux kernel, the following vulnerability has been resolved: ACPI: CPPC: Use access_width over bit_width for system memory accesses To align with ACPI 6.3+, since bit_width can be any 8-bit value, it cannot be depended on to be always on a clean 8b boundary. This was uncovered on the Cobalt 100 platform. SError Interrupt on CPU26, code 0xbe000011 -- SError CPU: 26 PID: 1510 Comm: systemd-udevd Not tainted 5.15.2.1-13 #1 Hardware name: MICROSOFT CORPORATION, BIOS MICROSOFT CORPORATION pstate: 62400009 (nZCv daif +PAN -UAO +TCO -DIT -SSBS BTYPE=--) pc : cppc_get_perf_caps+0xec/0x410 lr : cppc_get_perf_caps+0xe8/0x410 sp : ffff80

    bpf, sockmap: Prevent lock inversion deadlock in map delete elem

    In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Prevent lock inversion deadlock in map delete elem syzkaller started using corpuses where a BPF tracing program deletes elements from a sockmap/sockhash map. Because BPF tracing programs can be invoked from any interrupt context, locks taken during a map_delete_elem operation must be hardirq-safe. Otherwise a deadlock due to lock inversion is possible, as reported by lockdep: CPU0 CPU1 ---- ---- lock(&htab->buckets[i].lock); local_irq_disable();

  3. CVE-2024-25743

    CVE-2024-25743

    In the Linux kernel through 6.9, an untrusted hypervisor can inject virtual interrupts 0 and 14 at any point in time and can trigger the SIGFPE signal handler in userspace applications. This affects AMD SEV-SNP and AMD SEV-ES.

    Средний · CVSS 5.3EPSS 0,62%Нет опубликованного исправления

    Kernel: max page sharing of kernel samepage merging (ksm) may cause memory deduplication

    A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page.

    Kernel: nvme: memory corruption via unprivileged user passthrough

    A buffer overflow vulnerability was found in the NVM Express (NVMe) driver in the Linux kernel. Only privileged user could specify a small meta buffer and let the device perform larger Direct Memory Access (DMA) into the same buffer, overwriting unrelated kernel memory, causing random kernel crashes and memory corruption.

    Use-after-free in setup_async_work()

    A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work.

    Kernel: slab-use-after-free write in txend due to race condition

    A race condition occurred between the functions lmLogClose and txEnd in JFS, in the Linux Kernel, executed in different threads. This flaw allows a local attacker with normal user privileges to crash the system or leak internal kernel information.

    Kernel: x86/mm: a per-cpu entry area leak was identified through the init_cea_offsets function when prefetchnta and prefetcht2 instructions being used for the per-cpu entry area mapping to the user space

    A possible unauthorized memory access flaw was found in the Linux kernel's cpu_entry_area mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implemented in /arch/x86/mm/cpu_entry_area.c, which works through the init_cea_offsets() function when KASLR is enabled. However, despite this feature, there is still a risk of per-cpu entry area leaks. This issue could allow a local user to gain access to some important data with memory in an expected location and potentially escalate their privileges on th
