SUSE CVE-2025-21778

In the Linux kernel, the following vulnerability has been resolved: tracing: Do not allow mmap of persistent ring buffer When trying to mmap a trace instance buffer that is attached to reservemem, it would crash: BUG: unable to handle page fault for address: ffffe97bd00025c8 PF: supervisor read...

CVE-2022-49065

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix the svcdeferredevent trace class Fix a NULL deref crash that occurs when an svcrqst is deferred while the sunrpc tracing subsystem is enabled. svcrevisit sets dr-xprt to NULL, so it can't be relied upon in the...

CVE-2022-49065 SUNRPC: Fix the svc_deferred_event trace class

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix the svcdeferredevent trace class Fix a NULL deref crash that occurs when an svcrqst is deferred while the sunrpc tracing subsystem is enabled. svcrevisit sets dr-xprt to NULL, so it can't be relied upon in the...

CVE-2022-49065

In CVE-2022-49065, the Linux kernel SUNRPC service saw a NULL dereference when a sunrpc svc_rqst was deferred with tracing enabled. The fix avoids relying on dr->xprt after reevaluating the trace event format; the dr::addr is converted to a presentation address and stored as a string in TP_fas...

Specifically, when a VMA is split, the ring buffer unmap function can be call...

PT-2025-36278

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.16.0 Description A flaw exists in the Linux kernel related to tracing functionality. Specifically, insufficient bounds checking when handling strings longer than FTRACE BUFF MAX within the ftrace process regex...

SUSE CVE-2024-26920

In the Linux kernel, the following vulnerability has been resolved: tracing/trigger: Fix to return error if failed to alloc snapshot Fix registersnapshottrigger to return error code if it failed to allocate a snapshot instead of 0 success. Unless that, it will register snapshot trigger without an...

CVE-2021-47262

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ensure liveliness of nested VM-Enter fail tracepoint message Use the string machinery provided by the tracing subystem to make a copy of the string literals consumed by the "nested VM-Enter failed" tracepoint. A complet...

SUSE CVE-2016-9754

The ringbufferresize function in kernel/trace/ringbuffer.c in the profiling subsystem in the Linux kernel before 4.6.1 mishandles certain integer calculations, which allows local users to gain privileges by writing to the /sys/kernel/debug/tracing/buffersizekb file...

USN-5299-1: Linux kernel vulnerabilities

Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation could reassemble mixed encrypted and plaintext fragments. A physically proximate attacker could possibly use this issue to inject packets or exfiltrate selected fragments. CVE-2020-26147 It was discovered that the bluetooth...
