Vulnerability from variot
An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. macOS before 10.13.3 is affected. tvOS before 11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the "Kernel" component. It allows attackers to bypass intended memory-read restrictions via a crafted app. plural Apple A vulnerability exists in the product kernel component that bypasses memory read restrictions.An attacker could bypass the memory read limit through a crafted application. Apple iOS/WatchOS/tvOS/macOS are prone to multiple security vulnerabilities. An attacker can exploit these issues to execute arbitrary code with kernel or system privileges, gain sensitive information, bypass security restrictions and perform unauthorized actions and or cause a denial-of-service condition. Apple iOS, macOS High Sierra, tvOS, and watchOS are all products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices; macOS High Sierra is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system. watchOS is a smart watch operating system. The following products and versions are affected: Apple iOS prior to 11.2.5; macOS High Sierra prior to 10.13.3; watchOS prior to 4.2.2; tvOS prior to 11.2.5. MacOS sysctl_default_netsvctype_to_dscp_map and sysctl_dscp_to_wifi_ac_map stack leak through struct padding
CVE-2018-4093
The sysctls net.qos.default_netsvctype_to_dscp_map and net.qos.dscp_to_wifi_ac_map, implemented in sysctl_default_netsvctype_to_dscp_map() and sysctl_dscp_to_wifi_ac_map(), write arrays of elements of type struct netsvctype_dscp_map
from the stack to userspace. This struct type contains padding bytes:
/ * Network Service Type to DiffServ Code Point mapping / struct netsvctype_dscp_map { int netsvctype; u_int8_t dscp; / 6 bits diffserv code point / / 3 bytes padding / };
This issue was discovered using an AFL-based fuzzer, loosely based on TriforceAFL. These are the debug log diffs with different stack poison values (0xcc and 0xdd):

11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the \"Kernel\" component. It allows attackers to bypass intended memory-read restrictions via a crafted app. plural Apple A vulnerability exists in the product kernel component that bypasses memory read restrictions.An attacker could bypass the memory read limit through a crafted application. Apple iOS/WatchOS/tvOS/macOS are prone to multiple security vulnerabilities. \nAn attacker can exploit these issues to execute arbitrary code with kernel or system privileges, gain sensitive information, bypass security restrictions and perform unauthorized actions and or cause a denial-of-service condition. Apple iOS, macOS High Sierra, tvOS, and watchOS are all products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices; macOS High Sierra is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system. watchOS is a smart watch operating system. The following products and versions are affected: Apple iOS prior to 11.2.5; macOS High Sierra prior to 10.13.3; watchOS prior to 4.2.2; tvOS prior to 11.2.5. MacOS sysctl_default_netsvctype_to_dscp_map and sysctl_dscp_to_wifi_ac_map stack leak through struct padding \n\nCVE-2018-4093\n\n\nThe sysctls net.qos.default_netsvctype_to_dscp_map and net.qos.dscp_to_wifi_ac_map, implemented in sysctl_default_netsvctype_to_dscp_map() and sysctl_dscp_to_wifi_ac_map(), write arrays of elements of type `struct netsvctype_dscp_map` from the stack to userspace. This struct type contains padding bytes:\n\n/*\n * Network Service Type to DiffServ Code Point mapping\n */\nstruct netsvctype_dscp_map {\n int netsvctype;\n u_int8_t dscp; /* 6 bits diffserv code point */\n /* 3 bytes padding */\n};\n\n\nThis issue was discovered using an AFL-based fuzzer, loosely based on TriforceAFL. These are the debug log diffs with different stack poison values (0xcc and 0xdd):\n\n #### TESTCASE \u0027id:012874,src:012831,op:arith16,pos:30,val:be:+34,+cov\u0027\n[...]\n loaded 68 bytes fuzzdata\n[...]\n syscall(rax=0x600020000ca, args=[0x3, 0x3, 0x3, 0xea800f00000069, 0x10003, 0x0]); rsp=0x7ffee8bc9da8\n USER READ: addr 0x3, size 8, value 0x0000007200000004\n USER READ: addr 0xb, size 1, value 0x65\n USER READ: addr 0xc, size 1, value 0x00\n USER READ: addr 0xd, size 1, value 0x00\n USER READ: addr 0xe, size 1, value 0x00\n-USER WRITE: addr 0x3, size 8, value 0xcccccc0000000000\n-USER WRITE: addr 0xb, size 8, value 0xcccccc0a00000001\n-USER WRITE: addr 0x13, size 8, value 0xcccccc1800000002\n-USER WRITE: addr 0x1b, size 8, value 0xcccccc2200000003\n-USER WRITE: addr 0x23, size 8, value 0xcccccc2e00000004\n-USER WRITE: addr 0x2b, size 8, value 0xcccccc2000000005\n-USER WRITE: addr 0x33, size 8, value 0xcccccc1a00000006\n-USER WRITE: addr 0x3b, size 8, value 0xcccccc1000000007\n-USER WRITE: addr 0x43, size 8, value 0xcccccc1200000008\n+USER WRITE: addr 0x3, size 8, value 0xdddddd0000000000\n+USER WRITE: addr 0xb, size 8, value 0xdddddd0a00000001\n+USER WRITE: addr 0x13, size 8, value 0xdddddd1800000002\n+USER WRITE: addr 0x1b, size 8, value 0xdddddd2200000003\n+USER WRITE: addr 0x23, size 8, value 0xdddddd2e00000004\n+USER WRITE: addr 0x2b, size 8, value 0xdddddd2000000005\n+USER WRITE: addr 0x33, size 8, value 0xdddddd1a00000006\n+USER WRITE: addr 0x3b, size 8, value 0xdddddd1000000007\n+USER WRITE: addr 0x43, size 8, value 0xdddddd1200000008\n sysret\n OUT OF FUZZER INPUT DATA - REWINDING\n REWIND STATS: 1/sec\n REWIND!
