UBUNTU-CVE-2022-49339

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: unexport init-annotated seg6hmacinit EXPORTSYMBOL and init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated init. The access to a fre...

CVE-2022-49406

The CVE-2022-49406 entry is active in Linux kernel and concerns a deadlock in blk_ia_range_sysfs_show() caused by unnecessary use of the queue sysfs lock during reads. The fix, as described in the sources, is to remove the mutex_lock()/mutex_unlock() calls from blk_ia_range_sysfs_show(), since th...
