Last modified

CVE-2010-2530 is a vulnerability of currently unknown severity. Multiple integer signedness errors in smb_subr.c in the netsmb module in the kernel in NetBSD 5.0.2 and earlier, FreeBSD, and Apple Mac OS X allow local users to cause a denial of service (panic) via a negative size value in a /dev/nsmb ioctl operation, as demonstrated by a (1) SMBIOC_LOOKUP or (2) SMBIOC_OPENSESSION ioctl call.. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
