VUL-0: CVE-2019-19053: kernel-source: memory leak in the rpmsg_eptdev_write_iter() function in drivers/rpmsg/rpmsg_char.c
Last modified: 2021-07-07 19:14:55 UTC
A memory leak in the rpmsg_eptdev_write_iter() function in drivers/rpmsg/rpmsg_char.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering copy_from_iter_full() failures
The fix is needed only after the code change to iter read/write, commit
rpmsg: char: Migrate to iter versions of read and write
which was 4.20-rc1.
So only SLE15-SP2 needs the fix, and it was backported.
Reassigned back to security team.
