CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's SMC (Shared Memory Communications) implementation, where improper re-initialization of hash tables can lead to corruption of existing hash entries. This flaw poses a high risk as it may disrupt network communication and stability in systems utilizing SMC. Organizations running Linux kernel versions that include this vulnerability should prioritize patching to mitigate potential exploitation and ensure system integrity.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net/smc: Do not re-initialize smc hashtables INIT_HLIST_HEAD(&smc_v*_hashinfo.ht) are called after smc_nl_init(), proto_register() and sock_register(). This can lead to smc_v*_hashinfo.ht being reset even though hash entries already exist and are being used, possibly resulting in a corrupted list. Remove unnecessary and dangerous re-initialisation of smc_v*_hashinfo.ht in smc_init(); it is implicitly initialised to zero anyhow. Add HLIST_HEAD_INIT to the definitions for clarity.
