A flaw was found in the fixed buffer registration code for io_uring (io_sqe_buffer_register in io_uring/rsrc.c) in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation.

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.

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.

** DISPUTED ** An issue was discovered in BMC Patrol through 23.1.00. The agent's configuration can be remotely modified (and, by default, authentication is not required). Some configuration fields related to SNMP (e.g., masterAgentName or masterAgentStartLine) result in code execution when the agent is restarted. NOTE: the vendor's perspective is "These are not vulnerabilities for us as we have provided the option to implement the authentication."

An issue was discovered in the Linux kernel through 6.3.5. There is a use-after-free in xfs_btree_lookup_get_block in fs/xfs/libxfs/xfs_btree.c because fs/xfs/xfs_buf_item_recover.c does not perform buffer content verification when log replay is skipped.

An issue was discovered in BMC Patrol before 22.1.00. The agent's configuration can be remotely queried. This configuration contains the Patrol account password, encrypted with a default AES key. This account can then be used to achieve remote code execution.
