Title

Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count

Summary

In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count rmi_f3a_initialize() takes the GPIO count from the device query register (f3a->gpio_count = buf & RMI_F3A_GPIO_COUNT, range 0..127). rmi_f3a_map_gpios() then allocates gpio_key_map with min(gpio_count, TRACKSTICK_RANGE_END) == at most 6 entries, but rmi_f3a_attention() iterates the full gpio_count and dereferences gpio_key_map[i], and input->keycodemax is set to the full gpio_count while input->keycode points at the 6-entry allocation. A device that reports gpio_count > 6 therefore causes an out-of-bounds read of gpio_key_map[] on every attention interrupt, and out-of-bounds accesses through the input core's default keymap ioctls: EVIOCGKEYCODE reads past the buffer (leaking adjacent slab memory to user space) and EVIOCSKEYCODE writes a caller-controlled value past it, for any process able to open the evdev node, since input_default_getkeycode() and input_default_setkeycode() only bound the index against keycodemax. Size the keymap for the full gpio_count. The mapping loop is unchanged: it still assigns only the first min(gpio_count, TRACKSTICK_RANGE_END) entries; the remaining slots stay KEY_RESERVED (devm_kcalloc zero-fills) and are skipped when reporting.

GHSA-P39G-X9XH-7WQ9

Vulnerability from github – Published: 2026-07-25 12:31 – Updated: 2026-07-27 06:30

Details

In the Linux kernel, the following vulnerability has been resolved:

Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count

rmi_f3a_initialize() takes the GPIO count from the device query register (f3a->gpio_count = buf & RMI_F3A_GPIO_COUNT, range 0..127). rmi_f3a_map_gpios() then allocates gpio_key_map with min(gpio_count, TRACKSTICK_RANGE_END) == at most 6 entries, but rmi_f3a_attention() iterates the full gpio_count and dereferences gpio_key_map[i], and input->keycodemax is set to the full gpio_count while input->keycode points at the 6-entry allocation.

A device that reports gpio_count > 6 therefore causes an out-of-bounds read of gpio_key_map[] on every attention interrupt, and out-of-bounds accesses through the input core's default keymap ioctls: EVIOCGKEYCODE reads past the buffer (leaking adjacent slab memory to user space) and EVIOCSKEYCODE writes a caller-controlled value past it, for any process able to open the evdev node, since input_default_getkeycode() and input_default_setkeycode() only bound the index against keycodemax.

Size the keymap for the full gpio_count. The mapping loop is unchanged: it still assigns only the first min(gpio_count, TRACKSTICK_RANGE_END) entries; the remaining slots stay KEY_RESERVED (devm_kcalloc zero-fills) and are skipped when reporting.

13 vulnerabilities in this advisory, including CVE-2026-64277.

CVE-2026-64277

A flaw was found in the Linux kernel's `synaptics-rmi4` input driver. The `rmi_f3a_map_gpios()` function incorrectly allocates memory for the `gpio_key_map`, making it smaller than required. This allows a device reporting a specific `gpio_count` value to trigger an out-of-bounds read, leading to information disclosure by leaking adjacent slab memory to user space. Additionally, a local user with access to the `evdev` node can exploit this vulnerability to perform out-of-bounds writes with caller-controlled values, which may lead to further system compromise.

Summary

Important: kernel security, bug fix, and enhancement update

Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

kernel: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item (CVE-2025-68211)
kernel: ip6_tunnel: use skb_vlan_inet_prepare() in __ip6_tnl_rcv() (CVE-2026-23003)
kernel: netfilter: nft_set_pipapo_avx2: don't return non-matching entry on expiry (CVE-2026-43114)
kernel: sctp: purge outqueue on stale COOKIE-ECHO handling (CVE-2026-52924)
kernel: netfilter: xt_policy: fix strict mode inbound policy matching (CVE-2026-52920)
kernel: zram: fix use-after-free in zram_bvec_write_partial() (CVE-2026-53185)
kernel: netfilter: require Ethernet MAC header before using eth_hdr() (CVE-2026-53131)
kernel: netfilter: conntrack_irc: fix possible out-of-bounds read (CVE-2026-53268)
kernel: i2c: stub: Reject I2C block transfers with invalid length (CVE-2026-64191)
kernel: netfilter: ipset: fix race between dump and ip_set_list resize (CVE-2026-64189)
kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count (CVE-2026-64277)
kernel: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count (CVE-2026-64276)
kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer (CVE-2026-74581)

Bug Fix(es) and Enhancement(s):

[Rocky Linux-9.8.z] Intel CWF: CPU is unable to obtain cstate1 on idle system (JIRA:Rocky Linux-166118)
ss core dumped when there is an SCTP session [rhel-9.8.z] (JIRA:Rocky Linux-212398)

kernel: i2c: stub: Reject I2C block transfers with invalid length (CVE-2026-64191)
kernel: netfilter: ipset: fix race between dump and ip_set_list resize (CVE-2026-64189)
kernel: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page (CVE-2026-64320)
kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count (CVE-2026-64277)
kernel: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count (CVE-2026-64276)

Bug Fix(es) and Enhancement(s):

[Rocky Linux-RT] usb_hub_wq items may run on isolated+nohz_full cores (JIRA:Rocky Linux-178088)
SELinux TCP/MPTCP connect check bypass via TCP Fast Open [rhel-8.10.z] (JIRA:Rocky Linux-222800)
ss core dumped when there is an SCTP session [rhel-8.10.z] (JIRA:Rocky Linux-212400)
