Description

An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. An improper validation of an array index and out of bounds memory read in the Linux kernel's Integrated Services Digital Network (ISDN) functionality was found in the way users call ioctl CMTPCONNADD. A local user could use this flaw to crash the system or starve the resources causing denial of service.
