Summary
In the Linux kernel, the following vulnerability has been resolved: net: stmmac: enable all safety features by default In the original implementation of dwmac5 commit 8bf993a5877e ("net: stmmac: Add support for DWMAC5 and implement Safety Features") all safety features were enabled by default. Later it seems some implementations didn't have support for all the features, so in commit 5ac712dcdfef ("net: stmmac: enable platform specific safety features") the safety_feat_cfg structure was added to the callback and defined for some platforms to selectively enable these safety features. The problem is that only certain platforms were given that software support. If the automotive safety package bit is set in the hardware features register the safety feature callback is called for the platform, and for platforms that didn't get a safety_feat_cfg defined this results in the following NULL pointer dereference: [ 7.933303] Call trace: [ 7.935812] dwmac5_safety_feat_config+0x20/0x170 [stmmac] [ 7.941455] __stmmac_open+0x16c/0x474 [stmmac] [ 7.946117] stmmac_open+0x38/0x70 [stmmac] [ 7.950414] __dev_open+0x100/0x1dc [ 7.954006] __dev_change_flags+0x18c/0x204 [ 7.958297] dev_change_flags+0x24/0x6c [ 7.962237] do_setlink+0x2b8/0xfa4 [ 7.965827] __rtnl_newlink+0x4ec/0x840 [ 7.969766] rtnl_newlink+0x50/0x80 [ 7.973353] rtnetlink_rcv_msg+0x12c/0x374 [ 7.977557] netlink_rcv_skb+0x5c/0x130 [ 7.981500] rtnetlink_rcv+0x18/0x2c [ 7.985172] netlink_unicast+0x2e8/0x340 [ 7.989197] netlink_sendmsg+0x1a8/0x420 [ 7.993222] ____sys_sendmsg+0x218/0x280 [ 7.997249] ___sys_sendmsg+0xac/0x100 [ 8.001103] __sys_sendmsg+0x84/0xe0 [ 8.004776] __arm64_sys_sendmsg+0x24/0x30 [ 8.008983] invoke_syscall+0x48/0x114 [ 8.012840] el0_svc_common.constprop.0+0xcc/0xec [ 8.017665] do_el0_svc+0x38/0xb0 [ 8.021071] el0_svc+0x2c/0x84 [ 8.024212] el0t_64_sync_handler+0xf4/0x120 [ 8.028598] el0t_64_sync+0x190/0x194 Go back to the original behavior, if the automotive safety package is found to be supported in hardware enable all the features unless safety_feat_cfg is passed in saying this particular platform only supports a subset of the features.

Posteriormente, parece que algunas implementaciones no eran compatibles con todas las funciones, por lo que en el commit 5ac712dcdfef (\\\"net: stmmac: habilitar funciones de seguridad espec\u00edficas de la plataforma\\\") se a\u00f1adi\u00f3 la estructura safety_feat_cfg a la devoluci\u00f3n de llamada y se defini\u00f3 para algunas plataformas con el fin de habilitar selectivamente estas funciones de seguridad. El problema radica en que solo ciertas plataformas recibieron este soporte de software. Si el bit del paquete de seguridad automotriz est\u00e1 configurado en el registro de caracter\u00edsticas de hardware, se llama a la devoluci\u00f3n de llamada de la caracter\u00edstica de seguridad para la plataforma y, para las plataformas que no tienen un safety_feat_cfg definido, esto da como resultado la siguiente desreferencia de puntero NULL: [7.933303] Rastreo de llamada: [ 7.935812] dwmac5_safety_feat_config+0x20/0x170 [stmmac] [ 7.941455] __stmmac_open+0x16c/0x474 [stmmac] [ 7.946117] stmmac_open+0x38/0x70 [stmmac] [ 7.950414] __dev_open+0x100/0x1dc [ 7.954006] __dev_change_flags+0x18c/0x204 [ 7.958297] dev_change_flags+0x24/0x6c [ 7.962237] do_setlink+0x2b8/0xfa4 [ 7.965827] __rtnl_newlink+0x4ec/0x840 [ 7.969766] rtnl_newlink+0x50/0x80 [ 7.973353] rtnetlink_rcv_msg+0x12c/0x374 [ 7.977557] netlink_rcv_skb+0x5c/0x130 [ 7.981500] rtnetlink_rcv+0x18/0x2c [ 7.985172] netlink_unicast+0x2e8/0x340 [ 7.989197] netlink_sendmsg+0x1a8/0x420 [ 7.993222] ____sys_sendmsg+0x218/0x280 [ 7.997249] ___sys_sendmsg+0xac/0x100 [ 8.001103] __sys_sendmsg+0x84/0xe0 [ 8.004776] __arm64_sys_sendmsg+0x24/0x30 [ 8.008983] invoke_syscall+0x48/0x114 [ 8.012840] el0_svc_common.constprop.0+0xcc/0xec [ 8.017665] do_el0_svc+0x38/0xb0 [ 8.021071] el0_svc+0x2c/0x84 [ 8.024212] el0t_64_sync_handler+0xf4/0x120 [ 8.028598] el0t_64_sync+0x190/0x194 Regrese al comportamiento original, si se descubre que el paquete de seguridad automotriz es compatible con el hardware, habilite todas las funciones a menos que se pase safety_feat_cfg indicando que esta plataforma en particular solo admite un subconjunto de las funciones.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-476\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.14\",\"versionEndExcluding\":\"5.15.91\",\"matchCriteriaId\":\"D7106030-745D-4E41-92EA-B14D4942EE1E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.9\",\"matchCriteriaId\":\"ED5B6045-B1D2-4E03-B194-9005A351BCAE\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.2:rc1:*:*:*:*:*:*\",\"matchCriteriaId\":\"FF501633-2F44-4913-A8EE-B021929F49F6\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.2:rc2:*:*:*:*:*:*\",\"matchCriteriaId\":\"2BDA597B-CAC1-4DF0-86F0-42E142C654E9\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.2:rc3:*:*:*:*:*:*\",\"matchCriteriaId\":\"725C78C9-12CE-406F-ABE8-0813A01D66E8\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.2:rc4:*:*:*:*:*:*\",\"matchCriteriaId\":\"A127C155-689C-4F67-B146-44A57F4BFD85\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/120b8e527e07c65de7f2b9018dcd9d17e66f2427\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/aebf7e62708ba706ee7bf484c9023b15c214e92a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/fdfc76a116b5e9d3e98e6c96fe83b42d011d21d4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
