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.

kernel: perf/arm_dmc620: Fix hotplug callback leak in dmc620_pmu_init()

A resource leak flaw was found in the ARM DMC-620 PMU driver. If platformdriverregister fails during module initialization, the CPU hotplug callback registered earlier is not removed, leaving a dangling callback...

kernel: drivers/perf: hisi: Don't migrate perf to the CPU going to teardown

A logic error was found in the Linux kernel's HiSilicon PCIe performance monitoring driver in the CPU offline handling path. A local user can trigger this issue during CPU hotplug operations when the driver migrates performance monitoring context, potentially selecting the CPU being torn down as...

kernel: perf/smmuv3: Fix hotplug callback leak in arm_smmu_pmu_init()

A resource-handling flaw was found in the Linux kernel performance monitoring driver for ARM System Memory Management Unit version 3 in the way hotplug callbacks are registered during driver initialization. If driver registration fails, previously added CPU hotplug callbacks are not removed,...

kernel: Linux kernel: Local denial of service in marvell_cn10k perf driver

A flaw was found in the Linux kernel's marvellcn10k perf driver. A local user could exploit a hotplug callback leak in the tadpmuinit function. This vulnerability occurs when platformdriverregister fails to remove the callback, potentially leading to a denial of service...
