kernel: isdn: mISDN: Fix sleeping function called from invalid context

In the Linux kernel, the following vulnerability has been resolved: isdn: mISDN: Fix sleeping function called from invalid context The driver can call card-isac.release function from an atomic context. Fix this by calling this function after releasing the lock. The following log reveals it:...

CVE-2024-40915

A flaw was found in the kernelmappages function in RISC-V in the Linux Kernel, which is incorrectly designed to sleep in atomic contexts. This function cleared the valid bit in page table entries for deallocated pages to detect illegal memory accesses, but it utilized setmemory, which acquires a...
