An update for kernel is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1358 Final 1.0 1.0 2024-04-03 Initial 2024-04-03 2024-04-03 openEuler SA Tool V1.0 2024-04-03 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP1. The Linux Kernel, the operating system core itself. Security Fix(es): There may be information leakage vulnerabilities in the tcm_open function in drivers/staging/gmjstcm/tcm.c The tcm_open function does not set the memory block to 0 when allocating memory (kmalloc), which may lead to information leakage vulnerabilities.(CVE-2024-24891) There may be information leakage vulnerabilities in the tcm_read function in drivers/staging/gmjstcm/tcm.c The tcm_read function did not set this memory to 0 after calling the copy_to_user function, causing the user to read the information in the last tcm instruction.(CVE-2024-24898) An update for kernel is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
