In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Enable IRQ if do_ale() triggered in irq-enabled context
Unaligned access exception can be triggered in irq-enabled context such
as user mode, in this case do_ale() may call get_user() which may cause
sleep. Then we will get:
BUG: sleeping function called from invalid context at arch/loongarch/kernel/access-helper.h:7

CVE-2024-47738 Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.

CVE-2024-50111 [MEDIUM] LoongArch: Enable IRQ if do_ale() triggered in irq-enabled context
LoongArch: Enable IRQ if do_ale() triggered in irq-enabled context
FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

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