CVE-2024-57912·Kernel vulnerability

In the Linux kernel, the following vulnerability has been resolved: iio: pressure: zpa2326: fix information leak in triggered buffer The 'sample' local struct is used to push data to user space from a triggered buffer, but it has a hole between the temperature and the timestamp (u32 pressure, u16 temperature, GAP, u64 timestamp). This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

How to fix this CVE

Update your Linux kernel to version 6.12.10 or later to patch an information leak in the ZPA2326 pressure sensor driver's triggered buffer handling. The vulnerability allows uninitialized kernel memory to be exposed to userspace through sensor data readings. Administrators should prioritize this update for systems using Industrial I/O (IIO) pressure sensors, particularly those running kernel versions 6.7 through 6.12.9.

sudo dnf update kernel && sudo reboot

How to check if you are affected

  1. Step 1: Check your current kernel version by running 'uname -r' and compare against the affected range (6.7 to 6.12.9)
  2. Step 2: Verify if the ZPA2326 pressure sensor driver is loaded by running 'lsmod | grep zpa2326' or 'modinfo zpa2326'
  3. Step 3: Search kernel logs for IIO trigger buffer activity related to pressure sensors using 'dmesg | grep -i "zpa2326\|iio.*pressure"'
  4. Step 4: After patching, confirm the new kernel version with 'uname -r' and verify it shows 6.12.10 or later

FAQ

What is CVE-2024-57912?

CVE-2024-57912 is a memory disclosure vulnerability in the Linux kernel's ZPA2326 pressure sensor driver where uninitialized memory gaps within the triggered buffer data structure are sent to userspace, potentially leaking sensitive kernel information to local users.

Is CVE-2024-57912 being actively exploited?

No, this vulnerability is not listed on CISA's KEV catalog and no public exploits are currently available, though it remains a priority fix due to its information disclosure nature.

What versions of Kernel are affected by CVE-2024-57912?

Linux kernel versions 6.7 through 6.12.9 are vulnerable. Kernel 6.12.10 and later versions contain the fix.

How do I check if my server is vulnerable to CVE-2024-57912?

Run 'uname -r' to get your kernel version. If it falls between 6.7.0 and 6.12.9, your system is vulnerable. Additionally, check if the ZPA2326 driver is present with 'modinfo zpa2326' or 'lsmod | grep zpa2326'.

Does Defensia detect CVE-2024-57912?

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-2024-57912 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.
