| CVE-2023-53003 | 1 Linux | 1 Linux Kernel | 2025-04-01 | N/A | 7.8 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info The memory for llcc_driv_data is allocated by the LLCC driver. But when it is passed as the private driver info to the EDAC core, it will get freed during the qcom_edac driver release. So when the qcom_edac driver gets probed again, it will try to use the freed data leading to the use-after-free bug. Hence, do not pass llcc_driv_data as pvt_info but rather reference it using the platform_data pointer in the qcom_edac driver. | |||||

| In the Linux kernel, the following vulnerability has been resolved: net: nfc: Fix use-after-free in local_cleanup() Fix a use-after-free that occurs in kfree_skb() called from local_cleanup(). This could happen when killing nfc daemon (e.g. neard) after detaching an nfc device. When detaching an nfc device, local_cleanup() called from nfc_llcp_unregister_device() frees local->rx_pending and decreases local->ref by kref_put() in nfc_llcp_local_put(). In the terminating process, nfc daemon releases all sockets and it leads to decreasing local->ref. After the last release of local->ref, local_cleanup() called from local_release() frees local->rx_pending again, which leads to the bug. Setting local->rx_pending to NULL in local_cleanup() could prevent use-after-free when local_cleanup() is called twice. Found by a modified version of syzkaller.

| In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix receive ring space parameters when XDP is active The MTU setting at the time an XDP multi-buffer is attached determines whether the aggregation ring will be used and the rx_skb_func handler. This is done in bnxt_set_rx_skb_mode().

| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix use-after-free bug The bug can be triggered by sending a single amdgpu_gem_userptr_ioctl to the AMDGPU DRM driver on any ASICs with an invalid address and size. The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>. For example the following code: static void Syzkaller1(int fd) { struct drm_amdgpu_gem_userptr arg; int ret; arg.addr = 0xffffffffffff0000; arg.size = 0x80000000; /*2 Gb*/ arg.flags = 0x7; ret = drmIoctl(fd, 0xc1186451/*amdgpu_gem_userptr_ioctl*/, &arg); } Due to the address and size are not valid there is a failure in amdgpu_hmm_register->mmu_interval_notifier_insert->__mmu_interval_notifier_insert-> check_shl_overflow, but we even the amdgpu_hmm_register failure we still call amdgpu_hmm_unregister into amdgpu_gem_object_free which causes access to a bad address.
