CVE-2023-52457 serial: 8250: omap: Don't skip resource freeing if pm_runtime_resume_and_get() failed

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: omap: Don't skip resource freeing if pmruntimeresumeandget failed Returning an error code from .remove makes the driver core emit the little helpful error message: remove callback returned a non-zero value. This wil...

kernel: net: qcom/emac: race condition leading to use-after-free in emac_remove()

A race condition vulnerability was found in the Linux kernel's Qualcomm EMAC Gigabit Ethernet Controller when the user physically removes the device before cleanup in the emacremove function. This flaw can eventually result in a use-after-free issue, possibly leading to a system crash or other...

kernel: writeback: avoid use-after-free after removing device

In the Linux kernel, the following vulnerability has been resolved: writeback: avoid use-after-free after removing device When a disk is removed, bdiunregister gets called to stop further writeback and wait for associated delayed work to complete. However, wbinodewritebackend may schedule bandwid...

DEBIAN-CVE-2023-34324

Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by remova...

kernel: Kernel: NULL pointer dereference in Intel GVT-g debugfs during device removal

A flaw was found in the Linux kernel's Intel GVT-g Graphics Virtualization Technology debugfs component. When a device is removed through unbinding, the intelgvtdebugfsclean function may attempt to access a debugfs root that has already been deallocated, leading to a NULL pointer dereference. A...

kernel: scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add()

In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix possible resource leaks in mpt3sastransportportadd In mpt3sastransportportadd, if sasrphyadd returns error, sasrphyfree needs be called to free the resource allocated in sasenddevicealloc. Otherwise a kernel...

kernel: Linux kernel rt2x00 Wi-Fi driver: Denial of Service via memory leak during device removal

A flaw was found in the Linux kernel's rt2x00 Wi-Fi driver. A local user could exploit this vulnerability when a rt2x00 device is removed, as its associated channel surveys are not properly freed. This leads to a memory leak, which could result in a Denial of Service DoS due to resource exhaustio...
