CVE-2024-49963

Exploitation: none

CVSS base score: not scored

Vendor: Linux   Product: Linux

Description

In the Linux kernel, the following vulnerability has been resolved: mailbox: bcm2835: Fix timeout during suspend mode During noirq suspend phase the Raspberry Pi power driver suffer of firmware property timeouts. The reason is that the IRQ of the underlying BCM2835 mailbox is disabled and rpi_firmware_property_list() will always run into a timeout [1]. Since the VideoCore side isn't consider as a wakeup source, set the IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled during suspend-resume cycle. [1] PM: late suspend of devices complete after 1.754 msecs WARNING: CPU: 0 PID: 438 at drivers/firmware/raspberrypi.c:128 rpi_firmware_property_list+0x204/0x22c Firmware transaction 0x00028001 timeout Modules linked in: CPU: 0 PID: 438 Comm: bash Tainted: G C 6.9.3-dirty #17 Hardware name: BCM2835 Call trace: unwind_backtrace from show_stack+0x18/0x1c show_stack from dump_stack_lvl+0x34/0x44 dump_stack_lvl from __warn+0x88/0xec __warn from warn_slowpath_fmt+0x7c/0xb0 warn_slowpath_fmt from rpi_firmware_property_list+0x204/0x22c rpi_firmware_property_list from rpi_firmware_property+0x68/0x8c rpi_firmware_property from rpi_firmware_set_power+0x54/0xc0 rpi_firmware_set_power from _genpd_power_off+0xe4/0x148 _genpd_power_off from genpd_sync_power_off+0x7c/0x11c genpd_sync_power_off from genpd_finish_suspend+0xcc/0xe0 genpd_finish_suspend from dpm_run_callback+0x78/0xd0 dpm_run_callback from device_suspend_noirq+0xc0/0x238 device_suspend_noirq from dpm_suspend_noirq+0xb0/0x168 dpm_suspend_noirq from suspend_devices_and_enter+0x1b8/0x5ac suspend_devices_and_enter from pm_suspend+0x254/0x2e4 pm_suspend from state_store+0xa8/0xd4 state_store from kernfs_fop_write_iter+0x154/0x1a0 kernfs_fop_write_iter from vfs_write+0x12c/0x184 vfs_write from ksys_write+0x78/0xc0 ksys_write from ret_fast_syscall+0x0/0x54 Exception stack(0xcc93dfa8 to 0xcc93dff0) [...] PM: noirq suspend of devices complete after 3095.584 msecs

Lifecycle Timeline

Each milestone comes from a different source, so gaps between them are gaps in what those sources publish, not evidence that nothing happened. EPSS history for this CVE holds 4 points from 2026-11-05, tracked daily from 2026-11-05; earlier points are weekly, which dates a spike to within a week. Peak probability 0.3% on 2026-11-05.

What each source publishes about which product versions carry this vulnerability, kept as written rather than merged. Absence here means no source has published applicability data, not that nothing is affected.

Detection & Exploitation

Exploit / Pen Test
none published
Network IDS/IPS
none published
Host / SIEM
none published

Coverage across public collections only: Nuclei and OpenVAS NVT (scan); Snort and Suricata ET Open (network); Sigma and YARA (host/SIEM); Metasploit, Exploit-DB, public GitHub repositories and NVD exploit references (exploit). Absence here means nothing public was found, not that detection is impossible.
GitHub PoC repositories are collected automatically by PoC-in-GitHub (CC0) and filtered to repositories that are still online, contain code, and are starred or at least two weeks old. They are still not vetted: some are fakes and some are malware. Treat them as evidence that code was published, not as code to run.
NVD exploit references are links NVD's analysts tag as exploits; they confirm an exploit was referenced but carry no date. This product uses data from the NVD but is not endorsed or certified by the NVD.
OpenVAS coverage derives from the Greenbone Community Feed, made available under the Open Database License (ODbL) v1.0; its individual Vulnerability Tests are licensed GNU GPL v2.

No exploit-tool sightings recorded for this CVE.

Metasploit is dated by the first commit of the module file, Exploit-DB by its publication date, and GitHub repositories by their creation date. GitHub PoC repositories are filtered (still online, contain code, starred or at least two weeks old) but not vetted: some are fakes and some are malware, so they show that code was published, not that it works or is safe to run. Evidence tiers are explained on the About page.

Distribution Status

Where the distribution has shipped a fix, and in which version. Green means the release has resolved it, amber that it is still open. Data from the Debian Security Tracker, used under Debian's MIT / GPLv2+ terms. Debian is upstream of several other distributions, so a fix here often precedes theirs.

Not publicly exposed Fix on system upgrade 16 of 16

BOD 26-04 replaced the single KEV deadline of BOD 22-01 with four inputs: whether the asset is publicly exposed, KEV status, whether exploitation is automatable, and technical impact. Exposure belongs to each agency's asset, not to the CVE, so both outcomes are shown. Automatable and technical impact come from the CISA assessment above. Days are calendar days; for KEV entries the clock starts on the date it was added, and otherwise when the agency identifies the vulnerability on an asset. Agencies make the final exposure call asset by asset, and may set shorter timelines.
