openjdk: Enhance AWT ImagingLib (Oracle CPU 2026-07)

A flaw was found in OpenJDK. When the software processes certain images, a specific function fails to manage memory boundaries correctly. This can lead to the application attempting to access invalid memory or dereference a null pointer, which may cause the application to unexpectedly terminate...

SUSE CVE-2026-62432

The EVTCHNOPexpandarray hypercall checks for whether FIFO event channels are enabled, but without holding the correct lock. It can race with EVTCHNOPreset, resulting in dereferencing a NULL pointer...

JLSEC-2026-945 ImageMagick has NULL pointer dereference in ReadSFWImage after DestroyImageInfo (sfw.c)

In ReadSFWImage coders/sfw.c, when temporary file creation fails, readinfo is destroyed before its filename member is accessed, causing a NULL pointer dereference and crash. AddressSanitizer:DEADLYSIGNAL ================================================================= ==1414421==ERROR:...

JLSEC-2026-948 ImageMagick has NULL Pointer Dereference in ClonePixelCacheRepository via crafted image

A NULL pointer dereference in ClonePixelCacheRepository allows a remote attacker to crash any application linked against ImageMagick by supplying a crafted image file, resulting in Denial of Service. AddressSanitizer:DEADLYSIGNAL =================================================================...

CVE-2026-64258

A flaw was found in the fuse-uring component of the Linux kernel. When a copy operation to the userspace ring buffer fails, a request can be terminated improperly, leading to a NULL pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial...

CVE-2026-64489

A flaw was found in the ALSA Advanced Linux Sound Architecture ymfpci driver in the Linux kernel. This vulnerability occurs because the 'sndctlnew1' function, which allocates memory, may return a null value if memory allocation fails. The driver then attempts to use this null value without proper...

CVE-2026-64416

A flaw was found in the Linux kernel's memory management subsystem, specifically within the swap cgroup functionality. When a system is configured without swap, a corrupted page table entry PTE can lead to a null pointer dereference during process exit. This vulnerability allows a local attacker ...

PT-2026-66616

An incomplete fix for CVE-2026-15352 in the NASA core Flight System cFS Health and Safety HS application leaves a separate NULL pointer dereference reachable in versions through 7.0.1. An attacker who can trigger the affected command under specific conditions could cause the HS application to...

CVE-2026-64484

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture es1938 sound driver. This vulnerability arises when a memory allocation failure causes the sndctlnew1 function to return a null value. The sndes1938mixer function then attempts to use this null value without proper...

php security update

An update is available for php. This update affects Rocky Linux 9. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list PHP is an HTML-embedded scripting language commonly used with the Apache HTTP...

CVE-2026-64480

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA ice1712 driver. This vulnerability occurs because the sndctlnew1 function, which allocates memory, can return a null value upon failure, but the driver does not properly check for this. An attacker could potentially...

CVE-2026-64405

A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the hciconn module. This vulnerability occurs when the hciabortconn function attempts to process a pending connection while a critical pointer is unexpectedly null. This can lead to a null pointer dereference, causing...

CVE-2026-64486

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA cmipci component. This vulnerability occurs because the sndcmipcispdifcontrols function fails to check the return value of sndctlnew1, which can return a null pointer if memory allocation fails. A local attacker could...

CVE-2026-64295

A flaw was found in the Linux kernel's memory management mm component, specifically within the pageext iteration application programming interface API. When memory is dynamically added to the system a process known as 'hotplugging', the API does not properly validate memory page frame numbers PFN...

CVE-2026-64288

A flaw was found in the kernel's Kernel-based Virtual Machine KVM component for ARM64 architectures. A race condition can occur during the invalidation of the virtual Nested Translation Cache VNCR pseudo-TLB when a virtual CPU vcpu is being brought online or offline. This can lead to a null point...

CVE-2026-64263

A flaw was found in the Linux kernel's fuse-uring component. This vulnerability arises from the incorrect handling of cancelled entries, which are moved to a list where a subsequent operation unconditionally attempts to access a null pointer. A local attacker could exploit this flaw to trigger a...

CVE-2026-64404

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the isoconnbigsync function where a socket lock is temporarily released and re-acquired. During this window, the Bluetooth connection can be unexpectedly terminated. If the connection is torn down, the subseque...

CVE-2026-64297

A flaw was found in the Linux kernel. An unchecked return value in the moduleextendmaxpages function within the module decompression logic can lead to a null pointer dereference. This vulnerability can be triggered if memory allocation fails during module loading, resulting in a kernel oops. This...

CVE-2026-64482

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA Gravis Ultrasound GUS driver. When memory allocation fails, the sndctlnew1 function can return a null value. The sndgf1pcmvolumecontrol function does not properly check for this null return, leading to a null pointer...
