An update for kernel is now available for openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1368 Final 1.0 1.0 2023-06-27 Initial 2023-06-27 2023-06-27 openEuler SA Tool V1.0 2023-06-27 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP3. The Linux Kernel, the operating system core itself. Security Fix(es): An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process.(CVE-2023-31084) A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw could allow a local user to cause a denial of service problem.(CVE-2023-2985) An update for kernel is now available for openEuler-20.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
