This leads to a general protection fault when\naccessing a near-NULL address.\n\nThe root cause is that vidtv_mux_pid_ctx_init() does not check the\nreturn value of vidtv_mux_create_pid_ctx_once() for PMT section PIDs.\nIf the allocation fails, the PID context is never created, but init\nreturns success. The subsequent vidtv_mux_push_si() call then gets\nNULL from vidtv_mux_get_pid_ctx() and crashes.\n\nFix both the root cause (add error check in vidtv_mux_pid_ctx_init\nfor PMT PIDs) and add defensive NULL checks in vidtv_mux_push_si for\nall vidtv_mux_get_pid_ctx() calls.\n\n[1]\nOops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] SMP KASAN PTI\nKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\nWorkqueue: events vidtv_mux_tick\nRIP: 0010:vidtv_psi_ts_psi_write_into+0x54a/0xbc0 drivers/media/test-drivers/vidtv/vidtv_psi.c:197\nCall Trace:\n \n vidtv_psi_table_header_write_into drivers/media/test-drivers/vidtv/vidtv_psi.c:799 [inline]\n vidtv_psi_pmt_write_into+0x3b2/0xa70 drivers/media/test-drivers/vidtv/vidtv_psi.c:1231\n vidtv_mux_push_si+0x932/0xe80 drivers/media/test-drivers/vidtv/vidtv_mux.c:196\n vidtv_mux_tick+0xe9b/0x1480 drivers/media/test-drivers/vidtv/vidtv_mux.c:408", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "455bc12e7b73ab5a2dfcb47822e91e772bc6c42e" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "f0f5a1d7056980a0d512456fdb370cfb72bba86a" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "6df7e16d4f742c80add58995a6e69385b97aa9e6" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "cd923dadefadb9671b5ac341b672ff424d429c39" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "353d9578951dd38bc9679308f5b618ceed1f20fa" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "f965cf22dda7f512f4922415894c3e528269a4ae" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "b28b12be6e8910489e6800ed93ea4d41dfe19683" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "232e4b313ea342672edf8947e067c0de4328405b" }, { "version": "f90cf6079bf67988f8b1ad1ade70fc89d0080905", "status": "affected", "versionType": "git", "lessThan": "7d8bf3d8f91073f4db347ed3aa6302b56107499c" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "5.10", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "5.10" }, { "version": "5.10.260", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.211", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.177", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.144", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.95", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.18.37", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.18.*" }, { "version": "7.0.14", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "7.0.*" }, { "version": "7.1.2", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "7.1.*" }, { "version": "7.2", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
