UBUNTU-CVE-2023-53525

In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Allow UD qptype to join multicast only As for multicast: - The SIDR is the only mode that makes sense; - Besides PSUDP, other port spaces like PSIB is also allowed, as it is UD compatible. In this case qkey also needs t...

CVE-2023-53525

CVE-2023-53525 affects the Linux kernel RDMA CMA component. The issue is that multicast join logic previously allowed non-UD qp_type modes; the patch updates behavior to permit multicast joins only for UD qp_type and ensures qkey is set to a default when not provided, addressing an uninitialized ...

CVE-2022-50465

The CVE-2022-50465 issue is a Linux kernel ext4 fast-commit journal memory-leak: when the end of fast-commit journal blocks is unfinished, the unused tail space could leak uninitialized memory to disk. The published description states the fix is to zero out that unused space to prevent leakage. T...

CVE-2023-53462

Summary: The CVE concerns the Linux kernel HID/HSR driver (net/hsr/hsr_forward.c). A KMSAN-uninitialized-value access is reported in fill_frame_info() when VLAN (ETH_P_8021Q) is encountered, due to VLAN not being supported in the hsr driver. The issue is resolved by returning an error from fill_f...

CVE-2025-39904

Summary: The CVE-2025-39904 issue affects the Linux kernel’s kexec path for arm64 (and riscv per the patch set). A kexec_buf structure was previously declared without full initialization, and a field added by a prior patch could be read uninitialized on some architectures, triggering UBSAN invali...
