CVE-2022-48866·Kernel vulnerability

In the Linux kernel, the following vulnerability has been resolved: HID: hid-thrustmaster: fix OOB read in thrustmaster_interrupts Syzbot reported an slab-out-of-bounds Read in thrustmaster_probe() bug. The root case is in missing validation check of actual number of endpoints. Code should not blindly access usb_host_interface::endpoint array, since it may contain less endpoints than code expects. Fix it by adding missing validaion check and print an error if number of endpoints do not match expected number

How to fix this CVE

Update your Linux kernel to version 5.16.15 or later to resolve this out-of-bounds read vulnerability in the Thrustmaster HID driver. The issue stems from insufficient validation of USB endpoint counts during device initialization, which could lead to memory corruption. Systems running kernel versions 5.16.0 through 5.16.14 should prioritize patching to prevent potential system instability.

sudo dnf update kernel kernel-devel

How to check if you are affected

  1. Step 1: Check your current kernel version with `uname -r` and compare against the affected range 5.16.0-5.16.14
  2. Step 2: Verify if Thrustmaster HID devices are connected or previously configured by checking `lsusb | grep -i thrustmaster` or examining `/proc/bus/usb/devices`
  3. Step 3: Search system logs for HID initialization errors with `sudo journalctl -b | grep -i 'thrustmaster\|hid.*error\|slab-out-of-bounds'`
  4. Step 4: After patching, confirm the new kernel version is loaded with `uname -r` and reboot if necessary with `sudo reboot`

FAQ

What is CVE-2022-48866?

This vulnerability is an out-of-bounds memory read in the Linux kernel's Thrustmaster HID driver that occurs when a device reports fewer USB endpoints than the driver expects, potentially causing information disclosure or kernel crashes.

Is CVE-2022-48866 being actively exploited?

No, this vulnerability is not listed on the CISA KEV catalog and has no public exploit available. However, it should still be patched as it can cause system instability.

What versions of Kernel are affected by CVE-2022-48866?

Linux kernel versions 5.16.0 through 5.16.14 are vulnerable. The fix is included in version 5.16.15 and later.

How do I check if my server is vulnerable to CVE-2022-48866?

Run `uname -r` to check your kernel version. If the output shows 5.16.0 through 5.16.14, your system is vulnerable and requires immediate patching.

Does Defensia detect CVE-2022-48866?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If the Linux kernel is installed on a monitored server, CVE-2022-48866 will appear in your dashboard with remediation steps.

CVE-2024-42256CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: cifs: Fix server re-repick on subrequest retry When a subrequest is marked for needing retry, netfs will call cifs_prepare_write() which will make cifs repick the server for the op before renegotiating credits; it then calls cifs_issue_write() which invokes smb2_async_writev() - which re-repicks the server. If a different server is then selected, this causes the increment of server->in_flight to happen against one record and the decrement to happen against another, leading to misaccounting. Fix this by just removing the repick code in smb2_async_writev(). As this is only called from netfslib-driven code, cifs_prepare_write() should always have been called first, and so server should never be NULL and the preparatory step is repeated in the event that we do a retry. The problem manifests as a warning looking something like: WARNING: CPU: 4 PID: 72896 at fs/smb/client/smb2ops.c:97 smb2_add_credits+0x3f0/0x9e0 [cifs] ... RIP: 0010:smb2_add_credits+0x3f0/0x9e0 [cifs] ... smb2_writev_callback+0x334/0x560 [cifs] cifs_demultiplex_thread+0x77a/0x11b0 [cifs] kthread+0x187/0x1d0 ret_from_fork+0x34/0x60 ret_from_fork_asm+0x1a/0x30 Which may be triggered by a number of different xfstests running against an Azure server in multichannel mode. generic/249 seems the most repeatable, but generic/215, generic/249 and generic/308 may also show it.
CVE-2024-36031CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: keys: Fix overwrite of key expiration on instantiation The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expiry is only called when the pre-parser sets a specific expiry.
CVE-2024-38612CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix invalid unregister error path The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL is not defined. In that case if seg6_hmac_init() fails, the genl_unregister_family() isn't called. This issue exist since commit 46738b1317e1 ("ipv6: sr: add option to control lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible use-after-free and null-ptr-deref") replaced unregister_pernet_subsys() with genl_unregister_family() in this error path.
CVE-2024-38623CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Use variable length array instead of fixed size Should fix smatch warning: ntfs_set_label() error: __builtin_memcpy() 'uni->name' too small (20 vs 256)
CVE-2021-47548CVSS 9.8In the Linux kernel, the following vulnerability has been resolved: ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() The if statement: if (port >= DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8). However, if the value of port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off; because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6). To fix this possible array overflow, we first check port and if it is greater than or equal to DSAF_MAX_PORT_NUM, the function returns.
