The machine becomes unreachable by ping/SSH and requires a hardpower cycle. Root cause: commit d02198550423 ("x86/fpu: Improve crypto performance by making kernel-mode FPU reliably usable in softirqs") changed kernel_fpu_begin() to use local_bh_disable() instead of preempt_disable(). This sets SOFTIRQ_OFFSET in preempt_count during EFI runtime calls, making in_interrupt() return true in normal task context. The EFI graceful page fault handler efi_crash_gracefully_on_page_fault() uses in_interrupt() to bail out for faults in real interrupt context. With SOFTIRQ_OFFSET now set, the handler always bails out, leaving firmware page faults unhandled. This escalates to die() which also sees in_interrupt() as true and calls panic("Fatal exception in interrupt"), freezing the system. [Fix] Replace in_interrupt() with !in_task() in efi_crash_gracefully_on_page_fault(). This preserves the original intent of bailing for interrupts or NMI faults, while no longer falsely triggering from the FPU code path's local_bh_disable(). [Test Plan] 1. Boot affected HP machine with the patched 6.17-oem kernel. 2. Run:    $ sudo fwts uefirttime Without patch: system hard-freezes, requires power cycle. With patch: fwts completes (pass or fail), system remains responsive. [Where problems could occur] The change is in the EFI page fault handler (arch/x86/platform/efi/quirks.c). If !in_task() incorrectly identifies a real interrupt-context fault as task context, the handler would try to process it as an EFI firmware fault instead of letting the normal oops path handle it. This could mask real kernel bugs during interrupt-context EFI faults, though such faults are extremely rare. Also, a softirq taken between efi_rts_work.efi_rts_id assignment and the fpregs_lock() call could cause a page fault that gets misidentified. The use of !in_task() (which incorporates in_serving_softirq()) handles this window correctly.

[Bug 2154194] Re: [Jammy] Priority inversion problem in epoll for rt kernel

** Tags added: kernel-daily-bug -- You received this bug notification because you are subscribed to linux in Ubuntu. Matching subscriptions: Bgg, Bmail, Nb https://bugs.launchpad.net/bugs/2154194 Title: [Jammy] Priority inversion problem in epoll for rt kernel Status in linux package in Ubuntu: New Status in linux source package in Jammy: New Bug description: [SRU Justification] [Impact] The current epoll implementation in the 5.15 kernel utilizes a read-write semaphore (rwlock_t) to protect the ready event list. While this allows multiple producers to concurrently add items, it introduces a scheduling priority inversion vulnerability. If a high-priority consumer (such as a real-time thread calling epoll_wait) is blocked waiting for the exclusive write lock, it can be indefinitely stalled by a low-priority producer holding the read lock. This results in un-deterministic system stalls and latency spikes. The fix involves replacing rwlock_t with a standard spinlock_t one-to-one, and removing the now-redundant lockless helper functions (list_add_tail_lockless and chain_epi_lockless). This ensures that under real-time configurations, priority inheritance works correctly across the epoll subsystem, eliminating priority inversion. [Fix] Backport upstream commit: 0c43094f8cc9 ("eventpoll: Replace rwlock with spinlock") [Test Plan] Due to the nature of scheduling priority inversion, reproducing this bug reliably on demand is highly impractical. Because this race condition relies on erratic, non-deterministic scheduling micro-windows, a standard deterministic reproduction script cannot be provided. Therefore, validation relies on verifying that the replacement locking mechanism functions correctly, introduces no regressions, and scales safely under synthetic load. There is a test kernel available in the following ppa: https://launchpad.net/~munirsid/+archive/ubuntu/lp2154194 [Where Problems Could Occur] There is a trade-off in raw throughput for highly specific, synthetic workloads. As seen in the upstream commit description [0], in artificial benchmarks where hundreds of threads continuously spam epoll events, throughput can drop by ~38% due to serialization around the new spinlock. However, testing with realistic workloads (via perf bench epoll wait) actually demonstrates a performance improvement on x86 architectures. The regression potential for real-world production environments is considered low, as typical workloads do not exhibit continuous, uninterrupted event-spamming behavior. Moreover, the fix is strictly isolated to fs/eventpoll.c and alters no external kernel APIs. [Other Info] This bug was addressed upstream and has already been integrated into Noble and subsequent releases.

[Bug 2154125] Re: ubuntu desktop issue

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy.
