CVE-2025-37815

CVE-2025-37815 concerns the Linux kernel’s misc: microchip: pci1xxxx IRQ handling. The patch fixes a kernel panic during IRQ handler registration by acquiring the spinlock and saving the current interrupt state before processing the IRQ via generic_handle_irq. A previous fix substituted generic_h...

CVE-2022-49765

CVE-2022-49765 concerns the Linux kernel 9p transport. The issue arises from inconsistent lock state between p9 client structures and the trans_fd transport path. Specifically, p9_req_put() and p9_tag_remove() interactions cross IRQ contexts but the trans_fd path used a different lock, leading to...
