CVE-2024-56641

CVE-2024-56641 affects the Linux kernel (net/smc). The issue occurs when closing an SMC LGR connection: canceling close_work happens before it's initialized, triggering a WARN_ON in __flush_work. The fix is to initialize close_work before establishing the connection (as noted in the advisory). Re...

CVE-2024-53161

In the Linux kernel, the following vulnerability has been resolved: EDAC/bluefield: Fix potential integer overflow The 64-bit argument for the "get DIMM info" SMC call consists of memctrlidx left-shifted 16 bits and OR-ed with DIMM index. With memctrlidx defined as 32-bits wide the left-shift...

CVE-2024-53161

CVE-2024-53161 is tied to the Linux kernel EDAC/bluefield issue: the 64-bit get-DIMM-info SMC argument used mem_ctrl_idx left-shifted by 16 and OR’d with the DIMM index; with mem_ctrl_idx treated as 32-bit this can truncate the upper 16 bits, risking data loss. The advisory states the mem_ctrl_id...
