CVE-2022-49059

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: add flushworkqueue to prevent uaf Our detector found a concurrent use-after-free bug when detaching an NCI device. The main reason for this bug is the unexpected scheduling between the used delayed mechanism timer and...

CVE-2022-49059

The Linux kernel is affected by a concurrent use-after-free (UAF) vulnerability within the nfc: nci component. The root cause is unexpected scheduling between delayed mechanisms, specifically where a cleanup routine incorrectly assumes cmd_timer has been detached. This allows mod_timer to re-atta...

CVE-2021-47632

CVE-2021-47632 affects the Linux kernel on PowerPC where a spin_lock in change_page_attr() for set_memory caused spinlock recursion. The fix removes the read/modify/write sequence and the spin_lock(), and uses atomic handling of page-flag sets (_PAGE_KERNEL_RO/ROX/RW/RWX) by comparing flag sets t...
