CVE-2023-53528
CVE-2023-53528 affects the Linux kernel RDMA/rxe subsystem. The vulnerability arises from an unsafe drain-work-queue path in qp cleanup when create_qp does not fully complete; cleanup could attempt to drain send/recv queues before the queues exist, leading to a segfault. The fixed patch adds a gu...

In the Linux kernel, the following vulnerability has been resolved: nbd: fix incomplete validation of ioctl arg We tested and found an alarm caused by nbdioctl arg without verification. The UBSAN warning calltrace like below: UBSAN: Undefined behaviour in fs/buffer.c:1709:35 signed integer...
CVE-2023-53513
The CVE-2023-53513 issue is a Linux kernel vulnerability where incomplete validation of the nbd ioctl arg can trigger an i_size overflow when the arg is coerced to int (arg cast in nbd_ioctl /nbd_add_socket). The root cause is insufficient validation of large ioctl arguments, allowing an overflow...

CVE-2023-53486 fs/ntfs3: Enhance the attribute size check
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Enhance the attribute size check This combines the overflow and boundary check so that all attribute size will be properly examined while enumerating them. 169.181521 BUG: KASAN: slab-out-of-bounds in...
CVE-2023-53450
The CVE-2023-53450 entry concerns the Linux kernel ext4 subsystem. A malicious fuzzer that overwrites the ext4 superblock while mounted can set s_first_data_block to a very large value, causing the block-group calculation to underflow and trigger a BUG_ON. The fix changes the BUG_ON to ext4_warni...
