UBUNTU-CVE-2022-48653

In the Linux kernel, the following vulnerability has been resolved: ice: Don't double unplug aux on peer initiated reset In the IDC callback that is accessed when the aux drivers request a reset, the function to unplug the aux devices is called. This function is also called in the...

CVE-2022-48653

CVE-2022-48653 relates to the Linux kernel ice driver. The vulnerability arises from a double unplug of aux devices in the IDC callback (triggered when aux drivers request a reset and again in ice_prepare_for_reset), causing a scheduling while atomic BUG. The effect is a kernel panic/BUG rather t...

kernel: memory leak in ttusb_dec_exit_dvb() in media/usb/ttusb-dec/ttusb_dec.c

A memory leak issue was found in the Linux kernel media subsystem in the TTUSB DEC driver. It could occur in the ttusbdecexitdvb function because of the lack of a dvbfrontenddetach call. A local user could trigger this flaw by repeatedly plugging and unplugging the device, potentially causing a...

kernel: hid: Use After Free in asus_remove()

A use-after-free flaw was found in asuskbdbacklightset in drivers/hid/hid-asus.c in the Linux Kernel. This issue could allow an attacker to crash the system when plugging in or disconnecting a malicious USB device, which may lead to a kernel information leak problem...

The brcm80211 component in the Linux kernel through 6.5.10 has a brcmf_cfg80211_detach use-after-free in the device unplugging (disconnect the USB by hotplug) code. For physically proximate attackers with local access this "could be exploited in a real world scenario." This is related to brcmf_cfg80211_escan_timeout_worker in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.

QEMU: net: triggerable assertion due to race condition in hot-unplug

A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this time window to trigger an assertion and cause a denial of service...
