Title
accel/ivpu: Prevent recovery invocation during probe and resume
Summary
In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Prevent recovery invocation during probe and resume Refactor IPC send and receive functions to allow correct handling of operations that should not trigger a recovery process. Expose ivpu_send_receive_internal(), which is now utilized by the D0i3 entry, DCT initialization, and HWS initialization functions. These functions have been modified to return error codes gracefully, rather than initiating recovery. The updated functions are invoked within ivpu_probe() and ivpu_resume(), ensuring that any errors encountered during these stages result in a proper teardown or shutdown sequence. The previous approach of triggering recovery within these functions could lead to a race condition, potentially causing undefined behavior and kernel crashes due to null pointer dereferences.

Estas funciones se han modificado para devolver c\u00f3digos de error de forma elegante, en lugar de iniciar la recuperaci\u00f3n. Las funciones actualizadas se invocan dentro de ivpu_probe() e ivpu_resume(), lo que garantiza que cualquier error encontrado durante estas etapas d\u00e9 como resultado una secuencia de desmontaje o apagado adecuada. El enfoque anterior de activar la recuperaci\u00f3n dentro de estas funciones podr\u00eda conducir a una condici\u00f3n de ejecuci\u00f3n, lo que podr\u00eda causar un comportamiento indefinido y fallas del kernel debido a desreferencias de puntero nulo.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/accel/ivpu/ivpu_ipc.c\",\"drivers/accel/ivpu/ivpu_ipc.h\",\"drivers/accel/ivpu/ivpu_jsm_msg.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"45e45362e0955fc3b0b622e8a0d788097f3de902\",\"lessThan\":\"cac822772c4dc27a285f09caf30072ab76d2bf38\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"45e45362e0955fc3b0b622e8a0d788097f3de902\",\"lessThan\":\"362ef76020ea6219a4df4ac5b738672b59527239\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"45e45362e0955fc3b0b622e8a0d788097f3de902\",\"lessThan\":\"5eaa497411197c41b0813d61ba3fbd6267049082\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/accel/ivpu/ivpu_ipc.c\",\"drivers/accel/ivpu/ivpu_ipc.h\",\"drivers/accel/ivpu/ivpu_jsm_msg.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"6.8\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"6.8\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.11.11\",\"lessThanOrEqual\":\"6.11.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.2\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.13\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":4.7,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.0,\"impactScore\":3.6},{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":4.7,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.0,\"impactScore\":3.6}],\"ssvcV203\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"ssvcData\":{\"timestamp\":\"2025-10-01T20:02:29.458816Z\",\"id\":\"CVE-2024-56540\",\"options\":[{\"exploitation\":\"none\"},{\"automatable\":\"no\"},{\"technicalImpact\":\"partial\"}],\"role\":\"CISA Coordinator\",\"version\":\"2.0.3\"}}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-362\"},{\"lang\":\"en\",\"value\":\"CWE-476\"}]},{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-476\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.8\",\"versionEndExcluding\":\"6.11.11\",\"matchCriteriaId\":\"FF76D5FF-944B-4187-AE80-15327D64BB22\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.12\",\"versionEndExcluding\":\"6.12.2\",\"matchCriteriaId\":\"D8882B1B-2ABC-4838-AC1D-DBDBB5764776\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/362ef76020ea6219a4df4ac5b738672b59527239\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/5eaa497411197c41b0813d61ba3fbd6267049082\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/cac822772c4dc27a285f09caf30072ab76d2bf38\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}",
