CVE-2024-26999 serial/pmac_zilog: Remove flawed mitigation for rx irq flood

In the Linux kernel, the following vulnerability has been resolved: serial/pmaczilog: Remove flawed mitigation for rx irq flood The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmaczilog as ...

CVE-2024-26999

CVE-2024-26999 — Linux kernel (serial/pmac_zilog) A vulnerability in the Linux kernel’s pmac_zilog serial driver was mitigated by a patch that was later removed. The mitigation intended to stop IRQs entirely caused a crash when pmac_zilog is used as a serial console. Specifically, a pr_err() path...

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...

kernel: bpf: bpf_sk_storage: Fix invalid wait context lockdep report

A locking context violation was found in the BPF socket local storage implementation in the Linux kernel. The code attempts to allocate memory via kzalloc while holding a rawspinlock, which is unsafe for PREEMPTRT kernels. This can cause lockdep warnings and potential issues on real-time kernels...
