| 2025-02-27 | CVE-2025-21749 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: rose: lock the socket in rose_bind() syzbot reported a soft lockup in rose_loopback_timer(), with a repro calling bind() from multiple threads. rose_bind() must lock the socket to avoid this issue. | 5.5 |
| 2025-02-27 | CVE-2025-21773 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: etas_es58x: fix potential NULL pointer dereference on udev->serial The driver assumed that es58x_dev->udev->serial could never be NULL. While this is true on commercially available devices, an attacker could spoof the device identity providing a NULL USB serial number. That would trigger a NULL pointer dereference. Add a check on es58x_dev->udev->serial before accessing it. | 5.5 |
| 2025-02-27 | CVE-2025-21775 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: ctucanfd: handle skb allocation failure If skb allocation fails, the pointer to struct can_frame is NULL. | 5.5 |
| 2025-02-27 | CVE-2025-21776 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: USB: hub: Ignore non-compliant devices with too many configs or interfaces Robert Morris created a test program which can cause usb_hub_to_struct_hub() to dereference a NULL or inappropriate pointer: Oops: general protection fault, probably for non-canonical address 0xcccccccccccccccc: 0000 [#1] SMP DEBUG_PAGEALLOC PTI CPU: 7 UID: 0 PID: 117 Comm: kworker/7:1 Not tainted 6.13.0-rc3-00017-gf44d154d6e3d #14 Hardware name: FreeBSD BHYVE/BHYVE, BIOS 14.0 10/17/2021 Workqueue: usb_hub_wq hub_event RIP: 0010:usb_hub_adjust_deviceremovable+0x78/0x110 ...

We can prevent the problem from occurring by refusing to accept hub devices that violate the USB spec by having more than one configuration or interface. | 5.5 |
| 2025-02-27 | CVE-2025-21779 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Reject Hyper-V's SEND_IPI hypercalls if local APIC isn't in-kernel Advertise support for Hyper-V's SEND_IPI and SEND_IPI_EX hypercalls if and only if the local API is emulated/virtualized by KVM, and explicitly reject said hypercalls if the local APIC is emulated in userspace, i.e. | 5.5 |
| 2025-02-27 | CVE-2025-21780 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: avoid buffer overflow attach in smu_sys_set_pp_table() It malicious user provides a small pptable through sysfs and then a bigger pptable, it may cause buffer overflow attack in function smu_sys_set_pp_table(). | 7.8 |
| 2025-02-27 | CVE-2025-21782 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: orangefs: fix a oob in orangefs_debug_write I got a syzbot report: slab-out-of-bounds Read in orangefs_debug_write... | 7.1 |
| 2025-02-27 | CVE-2025-21783 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: gpiolib: Fix crash on error in gpiochip_get_ngpios() The gpiochip_get_ngpios() uses chip_*() macros to print messages. However these macros rely on gpiodev to be initialised and set, which is not the case when called via bgpio_init(). | 5.5 |
| 2025-02-27 | CVE-2025-21785 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array The loop that detects/populates cache information already has a bounds check on the array size but does not account for cache levels with separate data/instructions cache. | 7.8 |
| 2025-02-27 | CVE-2025-21787 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: team: better TEAM_OPTION_TYPE_STRING validation syzbot reported following splat [1] Make sure user-provided data contains one nul byte.
