Ubuntu.comUB:CVE-2023-52615CVE-2023-52615
In the Linux kernel, the following vulnerability has been resolved: hwrng:
core - Fix page fault dead lock on mmap-ed hwrng There is a dead-lock in
the hwrng device read path. This triggers when the user reads from
/dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page
fault triggers a recursive read which then dead-locks. Fix this by using a
stack buffer when calling copy_to_user.
