Technical Summary
This Red Hat security advisory (RHSA-2025:0059) covers four kernel vulnerabilities: CVE-2024-46713 fixes an AUX buffer serialization issue in the perf subsystem; CVE-2024-50208 addresses a bug in RDMA bnxt_re related to Level-2 PBL page setup; CVE-2024-50252 resolves a memory leak in the mlxsw spectrum_ipip module when changing remote IPv6 addresses; and CVE-2024-53122 mitigates a race condition during subflow creation in the mptcp_rcv_space_adjust function. These vulnerabilities affect the Linux kernel core in Red Hat Enterprise Linux 9 across multiple architectures and variants. Red Hat has released updated kernel packages that include fixes for these vulnerabilities and recommends applying the update followed by a system reboot.
Potential Impact
The vulnerabilities affect the Linux kernel, which is critical to system operation. The issues include a serialization flaw, a bug in RDMA page setup, a memory leak, and a race condition, which could lead to system instability, resource exhaustion, or incorrect kernel behavior. Red Hat rates the security impact as Important (high severity). There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated kernel packages for Red Hat Enterprise Linux 9 that address these vulnerabilities. Users should apply the available kernel update as described in the Red Hat advisory (RHSA-2025:0059) and reboot the system to ensure the fixes take effect. Patch status is confirmed as fixed by Red Hat. No additional mitigation steps are indicated beyond applying the official update and rebooting.
