Threats Tagged 'cve-2025-39933'

Red Hat issued a security advisory for multiple vulnerabilities in the Linux kernel packages included in Red Hat Enterprise Linux 9. The update addresses five distinct security issues affecting kernel components such as drm/xe, smb client, drm/vmwgfx, usb dwc3, and libceph. These vulnerabilities include compliance with safe access rules, verification of SMB client data parameters, command header size validation, race condition fixes, and use-after-free corrections. The advisory rates the update as important and requires a system reboot after applying the patches.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Linux kernel: Memory corruption in Squashfs due to incorrect block size calculation (CVE-2025-38415) * kernel: vsock/vmci: Clear the vmci transport packet properly when initializing it (CVE-2025-38403) * kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling (CVE-2025-38730) * kernel: smb: client: let recv_done verify data_offset, data_length and remaining_data_length (CVE-2025-39933) * kernel: mptcp: Use __sk_dst_get() and dst_dev_rcu() in mptcp_active_enable() (CVE-2025-40133) * kernel: Linux kernel: Out-of-bounds write in fbdev can lead to privilege escalation, information disclosure, or denial of service. (CVE-2025-40304) * kernel: Linux kernel: Information disclosure and denial of service via out-of-bounds read in font glyph handling (CVE-2025-40322) * kernel: svcrdma: use rc_pageoff for memcpy byte offset (CVE-2025-68811) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Linux kernel: xHCI driver isochronous event handling race condition leading to data loss or UAF (CVE-2025-37882) * kernel: Linux kernel use-after-free in eventpoll (CVE-2025-38349) * kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling (CVE-2025-38730) * kernel: Linux kernel: Denial of Service via out-of-bounds read in USB configuration parsing (CVE-2025-39760) * kernel: smb: client: let recv_done verify data_offset, data_length and remaining_data_length (CVE-2025-39933) * kernel: Linux kernel: Use-after-free in proc_readdir_de() can lead to privilege escalation or denial of service. (CVE-2025-40271) * kernel: Linux kernel: Out-of-bounds write in fbdev can lead to privilege escalation, information disclosure, or denial of service. (CVE-2025-40304) * kernel: Linux kernel ALSA USB audio driver: Buffer overflow leading to information disclosure and denial of service (CVE-2025-40269) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
