Debian Linux Security Advisory 5593-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset.
In onOptionsItemSelected of ManageApplications.java, there is a possible bypass of profile owner restrictions due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed.
