In the Linux kernel, the following vulnerability has been resolved: tracing: Fix sleeping function called from invalid context on RT kernel When setting bootparams="traceevent=initcall:initcallstart tpprintk=1" in the cmdline, the outputprintk was called, and the spinlockirqsave was called in the...

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

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...
