[SRU][Jammy/Kinetic][PATCH 0/1] CVE-2022-48502

[Yuxuan Luo]

[Impact]
An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem
does not properly check for correctness during disk reads, leading to an
out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c. 

[Backport]
It is a clean cherry pick.

[Test]
Compile and smoke tested.

[Potential Regression]
Expect very low regression potential.
