kernel: nfsd: call cache_put if xdr_reserve_space returns NULL

A flaw was found in the Linux kernel's Network File System Daemon nfsd component. This vulnerability occurs when the system attempts to allocate buffer space but fails, yet a related lookup operation succeeds. This leads to a resource leak where a cache entry is acquired but not properly released...

SUSE CVE-2025-37880

In the Linux kernel, the following vulnerability has been resolved: um: work around schedyield not yielding in time-travel mode schedyield by a userspace may not actually cause scheduling in time-travel mode as no time has passed. In the case seen it appears to be a badly implemented userspace...

CVE-2025-37880

CVE-2025-37880 affects the Linux kernel where sched_yield may not yield in time-travel mode due to a poorly implemented userspace spinlock in ASAN. The fix adds accounting of time to the process on every sched_yield to ensure proper scheduling. Impact can be extreme slowdown or deadlock depending...

CVE-2025-37854

CVE-2025-37854 affects the Linux kernel drm/amdkfd path. A use-after-free race occurs when mode1 reset is used to recover a hung GPU: after KFD signals user space to abort, the cleanup may free or reuse system memory (and VRAM) still in use by user queues, potentially corrupting data structures a...

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fix region HPA ordering validation Some regions may not have any address space allocated. Skip them when validating HPA order otherwise a crash like the following may result: devmcxladdregion: cxlacpi cxlacpi.0:...

Enable Kernel ASLR

Address-space layout randomization ASLR randomly arranges the positions of the stack, function libraries, and programs to slightly different positions each time. As a result, the correct positions cannot be guessed, and buffer overflow attacks fail. In the Linux kernel, ASLR is classified into...

Receive Remote rsyslog Messages Only on A Specified Log Host

By default, rsyslog does not listen on log messages from a remote system. Log message listening via TCP is performed in a similar way to log message listening via UDP, both requiring rsyslog to load a module, that is, the imtcp.so module and the imudp.so module respectively. The TCP/UDP port to b...

Ensure That the Drive Space Threshold Is Correct

If the drive space is fully occupied by auditd logs, services may fail to be executed. Therefore, set related configuration items in advance to prevent serious system issues caused by low drive space. The following items in the /etc/audit/auditd.conf file have been configured with default values ...

Configure the SSH Service Log Level Properly

SSH provides multiple log output levels, such as QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. A higher log level such as QUIET or FATAL prints less log information. This saves drive space but hinders administrators from auditing and tracing SSH events. Conversely, a lowe...
