kernel: powerpc/smp: do not decrement idle task preempt count in CPU offline

A vulnerability was found in the Linux kernel's powerpc/smp architecture, where the idle task's preemption count was incorrectly decremented during the CPU offline process. This issue caused a "scheduling while atomic" error when a CPU was offlined and then onlined again, leading to potential...

kernel: tty: n_gsm: avoid call of sleeping functions from atomic context

REJECTED CVE In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: avoid call of sleeping functions from atomic context...

kernel: i2c: core: Run atomic i2c xfer when !preemptible

In the Linux kernel, the following vulnerability has been resolved: i2c: core: Run atomic i2c xfer when !preemptible Since bae1d3a05a8b, i2c transfers are non-atomic if preemption is disabled. However, non-atomic i2c transfers require preemption e.g. in waitforcompletion while waiting for the DMA...

kernel: debugobjects: Don't wake up kswapd from fill_pool()

A locking issue was found in the Linux kernel's debugobjects subsystem. The fillpool function uses GFPATOMIC allocation flags, which attempt to wake up kswapd and acquire kswapdwait::lock. Since fillpool may be called with arbitrary locks already held, this can trigger lockdep warnings about...

kernel: rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic()

A locking violation was found in the Linux kernel RCU-tasks subsystem's callback list initialization. During system boot, the initialization code calls prinfo while holding the rtp-cbsgbllock spinlock, causing a potentially sleeping function to be called in atomic context, which results in kernel...

AZL-52486 CVE-2024-50111 affecting package kernel 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Enable IRQ if doale triggered in irq-enabled context Unaligned access exception can be triggered in irq-enabled context such as user mode, in this case doale may call getuser which may cause sleep. Then we will get: BU...

UBUNTU-CVE-2024-50138

In the Linux kernel, the following vulnerability has been resolved: bpf: Use rawspinlockt in ringbuf The function bpfringbufreserve is invoked from a tracepoint, which disables preemption. Using spinlockt in this context can lead to a "sleep in atomic" warning in the RT variant. This issue is...

CVE-2024-50138

CVE-2024-50138 concerns the Linux kernel BPF ringbuf handling. The issue arises when __bpf_ringbuf_reserve is invoked from a tracepoint with preemption disabled, where using spinlock_t could trigger a “sleep in atomic” warning on RT variants. The root cause is the use of a spinlock_t in the ringb...

Researchers Uncover Python Package Targeting Crypto Wallets with Malicious Code

Cybersecurity researchers have discovered a new malicious Python package that masquerades as a cryptocurrency trading tool but harbors functionality designed to steal sensitive data and drain assets from victims' crypto wallets. The package, named "CryptoAITools," is said to have been distributed...

CVE-2024-50067 uprobe: avoid out-of-bounds memory access of fetching args

In the Linux kernel, the following vulnerability has been resolved: uprobe: avoid out-of-bounds memory access of fetching args Uprobe needs to fetch args into a percpu buffer, and then copy to ring buffer to avoid non-atomic context problem. Sometimes user-space strings, arrays can be very large,...

CVE-2024-50067

CVE-2024-50067 relates to the Linux kernel, where a vulnerability in upstream probing (uprobe) could cause an out-of-bounds memory access when fetching arguments for tracing. The issue arises because data may be larger than the per-CPU buffer size (a page), and store_trace_args() may not detect d...
