| CVE-2026-3832 | 2 Gnu, Redhat | 6 Gnutls, Enterprise Linux, Hardened Images and 3 more | 2026-05-11 | 3.7 Low |
| A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust. | ||||

| CVE-2022-49583 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-05-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: iavf: Fix handling of dummy receive descriptors Fix memory leak caused by not handling dummy receive descriptor properly. iavf_get_rx_buffer now sets the rx_buffer return value for dummy receive descriptors. Without this patch, when the hardware writes a dummy descriptor, iavf would not free the page allocated for the previous receive buffer. This is an unlikely event but can still happen.

| CVE-2022-49404 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-05-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Fix potential integer multiplication overflow errors When multiplying of different types, an overflow is possible even when storing the result in a larger type. This is because the conversion is done after the multiplication. So arithmetic overflow and thus in incorrect value is possible. Correct an instance of this in the inter packet delay calculation. Fix by ensuring one of the operands is u64 which will promote the other to u64 as well ensuring no overflow. | ||||

| CVE-2022-49389 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-05-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usb: usbip: fix a refcount leak in stub_probe() usb_get_dev() is called in stub_device_alloc(). When stub_probe() fails after that, usb_put_dev() needs to be called to release the reference. Fix this by moving usb_put_dev() to sdev_free error path handling. Find this by code review. | ||||
| CVE-2022-49334 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-05-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mm/huge_memory: Fix xarray node memory leak If xas_split_alloc() fails to allocate the necessary nodes to complete the xarray entry split, it sets the xa_state to -ENOMEM, which xas_nomem() then interprets as "Please allocate more memory", not as "Please free any unnecessary memory" (which was the intended outcome). It's confusing to use xas_nomem() to free memory in this context, so call xas_destroy() instead. | ||||

| In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: fix possible null-ptr-deref in arm_smmu_device_probe() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code. | ||||
