EUVD-2026-55287

In the Linux kernel, the following vulnerability has been resolved: binfmtmisc: set haveexecfd only once the interpreter is opened loadmiscbinary raises bprm-haveexecfd as soon as it sees the 'O' or 'C' flag. This happens well before it opens the interpreter. If that open fails the flag stays set...

CVE-2026-68186

The CVE-2026-68186 issue affects the Linux kernel’s binfmt_misc handling. load_misc_binary() sets bprm->have_execfd when it encounters the O/C flag, before the interpreter is opened, which could cause a NULL dereference in begin_new_exec() if an interpreter open fails and a later format is cho...

CVE-2026-68176 tracing: Fix mmiotrace possible NULL dereferencing of hiter->dev

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix mmiotrace possible NULL dereferencing of hiter-dev If the mmiopipeopen fails to find a PCI device, the hiter-dev will be assigned to NULL. The mmiotrace read function dereferences the hiter-dev if hiter exists. Chang...

CVE-2026-68176

The CVE-2026-68176 entry concerns the Linux kernel tracing subsystem (mmiotrace) where a NULL dereference could occur if mmio_pipe_open() fails to locate a PCI device and hiter->dev is NULL. The read() path previously dereferenced hiter->dev without verifying it; the fix adds a check for hi...

In the Linux kernel, the following vulnerability has been resolved: net: sxgbe: fixed the potential NULL dereference in sxgberx. Currently, when skb is null, the driver prints an error and then dereferences skb on the next line. To fix this, we need to add a ‘break’ after the error message, so th...
