26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Use kzalloc for sev ioctl interfaces to prevent kernel data leak For some sev ioctl interfaces, the length parameter that is passed maybe less than or equal to SEV_FW_BLOB_MAX_SIZE, but larger than the data that PSP firmware returns. In this case, kmalloc will allocate memory that is the size of the input rather than the size of the data. Since PSP firmware doesn't fully overwrite the allocated buffer, these sev ioctl interface ma... • https://git.kernel.org/stable/c/eaf78265a4ab33935d3a0f1407ce4a91aac4d4d5 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: Use del_timer_sync() before freeing While looking at a crash report on a timer list being corrupted, which usually happens when a timer is freed while still active. This is commonly triggered by code calling del_timer() instead of del_timer_sync() just before freeing. One possible culprit is the hci_qca driver, which does exactly that. Eric mentioned that wake_retrans_timer could be rearmed via the work queue, so also mo... • https://git.kernel.org/stable/c/0ff252c1976da5d80db1377eb39b551931e61826 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: zsmalloc: fix races between asynchronous zspage free and page migration The asynchronous zspage free worker tries to lock a zspage's entire page list without defending against page migration. Since pages which haven't yet been locked can concurrently migrate off the zspage page list while lock_zspage() churns away, lock_zspage() can suffer from a few different lethal races. It can lock a page which no longer belongs to the zspage and unsafe... • https://git.kernel.org/stable/c/77ff465799c60294e248000cd22ae8171da3304c •
