CVE-2024-36288
A flaw in the Linux kernel’s SUNRPC subsystem caused an improper loop termination in the gss_free_in_token_pages() function, leading to a kernel memory corruption error. The issue has been fixed in the kernel source. Users should update to a patched kernel version.
An official fix is available, so this entry is kept for 30 days and then removed automatically.
Who is affected
Linux kernel, including version 6.10.0 and earlier releases that contain the vulnerable code. System administrators and users running affected kernels are impacted.
Real-world impact
An attacker could exploit the memory corruption to gain arbitrary code execution with kernel privileges, potentially taking full control of the affected system.
Why this severity
The CVSS score of 9.8 reflects that the vulnerability can be exploited remotely over the network, requires no user interaction, and compromises confidentiality, integrity, and availability of the system.
What to do about it
- 011. Update the Linux kernel to version 6.10.0 or later, which includes the fix for gss_free_in_token_pages().
- 022. Reboot the system to load the updated kernel.
