CVE-2024-53075 riscv: Prevent a bad reference count on CPU nodes

In the Linux kernel, the following vulnerability has been resolved: riscv: Prevent a bad reference count on CPU nodes When populating cache leaves we previously fetched the CPU device node at the very beginning. But when ACPI is enabled we go through a specific branch which returns early and does...

CVE-2024-53075

The CVE-2024-53075 entry concerns the Linux kernel riscv path used while populating cache leaves. Root cause: when ACPI is enabled, the code path early-returns and omits of_node_put for the CPU device node, creating a potential bad reference count. The fix moves the CPU node initialization to aft...

CVE-2024-11263

When the Global Pointer GP relative addressing is enabled CONFIGRISCVGP=y, the gp reg points at 0x800 bytes past the start of the .sdata section which is then used by the linker to relax accesses to global symbols...

USN-7089-6 linux-gke vulnerabilities

Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing. A local attacker could possibly use this to cause a denial of service. CVE-2024-25741 Several security issues were discovered in the Linux kernel. An...

CVE-2022-49001

CVE-2022-49001 describes a race condition in the Linux kernel riscv path where, during vmap stack overflow handling, multiple harts can contend on the same shadow stack. The root cause is a race between switching to the shadow stack and calling get_overflow_stack() when more than one hart uses th...
