Description
This security bulletin contains information about 4 vulnerabilities.
1) Memory leak (CVE-ID: CVE-2024-50302)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:A/U:Green
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the hid_alloc_report_buf() function in drivers/hid/hid-core.c. A local user can perform a denial of service (DoS) attack.
Note, the vulnerability is being actively exploited in the wild against Android devices.
2) Out-of-bounds write (CVE-ID: CVE-2024-53197)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a local user to compromise the affected system.
The vulnerability exists due to an out-of-bounds write error within the snd_usb_create_quirk(), snd_usb_extigy_boot_quirk(), mbox2_setup_48_24_magic() and snd_usb_mbox2_boot_quirk() functions in sound/usb/quirks.c. A local user can trigger an out-of-bounds write and execute arbitrary code on the system.
Note, the vulnerability is being actively exploited against Android devices.
3) Improper locking (CVE-ID: CVE-2024-57807)
CWE-ID: CWE-667 - Improper Locking
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the megasas_aen_polling() function in drivers/scsi/megaraid/megaraid_sas_base.c. A local user can perform a denial of service (DoS) attack.
4) Use-after-free (CVE-ID: CVE-2024-57979)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the ptp_ocp_complete() function in drivers/ptp/ptp_ocp.c, within the DEFINE_MUTEX(), pps_cdev_pps_fetch(), pps_cdev_ioctl(), pps_cdev_compat_ioctl(), pps_device_destruct(), pps_register_cdev(), pps_unregister_cdev(), EXPORT_SYMBOL() and pps_init() functions in drivers/pps/pps.c, within the pps_kc_bind() and pps_kc_remove() functions in drivers/pps/kc.c, within the pps_add_offset(), pps_register_source() and pps_event() functions in drivers/pps/kapi.c, within the parport_irq() function in drivers/pps/clients/pps_parport.c, within the pps_tty_dcd_change(), pps_tty_open() and pps_tty_close() functions in drivers/pps/clients/pps-ldisc.c, within the pps_ktimer_exit() and pps_ktimer_init() functions in drivers/pps/clients/pps-ktimer.c, within the pps_gpio_probe() function in drivers/pps/clients/pps-gpio.c. A local user can escalate privileges on the system.
