Ubuntu.comUB:CVE-2021-47351CVE-2021-47351
In the Linux kernel, the following vulnerability has been resolved: ubifs:
Fix races between xattr_{set|get} and listxattr operations UBIFS may occur
some problems with concurrent xattr_{set|get} and listxattr operations,
such as assertion failure, memory corruption, stale xattr value[1]. Fix it
by importing a new rw-lock in @ubifs_inode to serilize write operations on
xattr, concurrent read operations are still effective, just like ext4. [1]
