CVE-2024-40980

CVE-2024-40980 concerns the Linux kernel: in drop_monitor, a spin_lock is used inside trace_drop_common() with preemption disabled, which can sleep in RT contexts. The vulnerability arises from acquiring a spin_lock while in a preempt-disabled/RT path, causing a potential sleeping-in-atomic conte...

CVE-2024-40980

In the Linux kernel, the following vulnerability has been resolved: dropmonitor: replace spinlock by rawspinlock tracedropcommon is called with preemption disabled, and it acquires a spinlock. This is problematic for RT kernels because spinlocks are sleeping locks in this configuration, which...

CVE-2024-40966 tty: add the option to have a tty reject a new ldisc

In the Linux kernel, the following vulnerability has been resolved: tty: add the option to have a tty reject a new ldisc ... and use it to limit the virtual terminals to just NTTY. They are kind of special, and in particular, the "conwrite" routine violates the "writes cannot sleep" rule that som...

CVE-2024-40915

The CVE-2024-40915 issue affects the Linux kernel on riscv, where __kernel_map_pages() (a debugging page-table helper) used __set_memory() to flip the valid bit of page-table entries. __set_memory() takes init_mm’s semaphore and can sleep, but __kernel_map_pages() may be called in atomic context,...
