Linux Kernel Security Vulnerabilities

The Linux kernel version 6.8 contains security vulnerabilities. These vulnerabilities stem from the pvrmmumapsgl interface not correctly returning a failure to mapping operations. As a result, the pvrmmumap interface continues to execute instead of returning an error, which may lead to null point...

Linux Kernel Security Vulnerabilities

There are security vulnerabilities in Linux kernels versions 6.1.54 and earlier, 6.5.4 and earlier than 6.6, as well as 6.6 itself. These vulnerabilities stem from the virtiogpufencealloc function, which returns NULL under memory pressure. As a result, the caller does not check this value and...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.8 contains security vulnerabilities. These vulnerabilities arise from the fact that the link between the VMA resources is not released before destroying the page table in xevmcloseandput. As a result, concurrent threads may deallocate shared buffer objects and then call...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises when the user space provides full-speed descriptors, and FunctionFS runs at a higher speed. In this case, the FUNCTIONFSENDPOINTDESC ioctl only selects the endpoint descriptor at the current speed, without retreating to...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.5 contains a security vulnerability. This vulnerability stems from the fact that in serialcoreunregisterport, when port-portdev is empty, the function passes it without checking, leading to a null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.8 contains security vulnerabilities. These vulnerabilities stem from the failure to check the CQE during the removal of the XSK TX queue. This could result in a NULL CQE being passed to the mlx5exskfilltimestamp function, leading to a null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.6 contains a security vulnerability. This vulnerability arises from the mtkethsoc driver, which allocates a dummy netdev after registering the MAC netdev and adds shared NAPIs. This results in a null pointer derefrence when network devices become visible prematurely,...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.16 contains a security vulnerability. This vulnerability arises from the max30102 interrupt handler referencing an empty activescanmask when a buffer is not enabled, which may lead to null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.16 contains a security vulnerability. This vulnerability arises from improper handling of SVE features within the VM scope when vCPU initialization fails. As a result, subsequent vCPUs skip SVE settings and use an empty svestate value. This could lead to a null pointer...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.6 contains security vulnerabilities. These vulnerabilities stem from the KVM x86/mmu failing to terminate the traversal of shadow page tables immediately when the root is invalid or dummy root. When memslot creation competes with L2’s stage-2 page errors, the shadow pag...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.18 contains a security vulnerability. This vulnerability arises from passing NULL as a register address during register registration for the divided clock. The Common Clock Framework calls clkdividerrecalcrate, which dereferences that address via readl. As a result, the...

Linux Kernel Security Vulnerabilities

The Linux kernel versions 6.16.8 to 6.17 contain security vulnerabilities. These vulnerabilities arise when user integrity metadata is combined with direct I/O polling. In this scenario, IOCBHASMETADATA reserves iocb-private as uiometa, while iocbbioiopoll treats it as bio. This leads to calls to...

Linux Kernel Security Vulnerabilities

The Linux kernel version 7.0 contains a security vulnerability. This vulnerability stems from the fact that the datcondsetstoragekey function in KVM s390 does not check the NULL oldkey passed by the caller. As a result, when the pagecondsetstoragekey function is called, a null pointer dereferenci...

Linux Kernel Security Vulnerabilities

The Linux kernel versions 5.10.266 to 5.11, 5.15.217 to 5.16, and 7.2 contain security vulnerabilities. These vulnerabilities stem from a race condition between the tbremovework and tbdomainremove functions in the Thunderbolt driver. The tbfreeunpluggedxdomains function is called without checking...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.17 contains a security vulnerability. This vulnerability arises from the fact that when setting the Rx coalesce parameters before the interface is initially opened, the bcmgenetsetrxcoalesce function accesses ring-priv which points to NULL. This leads to a null pointer...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.15 contains a security vulnerability. This vulnerability stems from the ofoverlayfdtapply function in of/overlay, which checks the return value of idralloc before execution. If this function fails, a negative ID passes the check, and uninitialized ovcs-ovcslist is...

Linux Kernel Security Vulnerabilities

The Linux kernel version 3.7 contains security vulnerabilities. These vulnerabilities stem from synchronization conflicts between nfcllcpsocketrelease and nfcllcpacceptdequeue. This can lead to concurrent deconnection and the release of the same sub-socket. As a result, the socket may be reused...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.10 contains security vulnerabilities. These vulnerabilities stem from the vmgenid driver, which does not set the driverdata before registering the notification handler. When an interrupt occurs, the handler dereferes a null pointer, which may lead to kernel crashes...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.1 contains a security vulnerability. This vulnerability stems from the fact that in the file drivers/net/dsa/mt7530-mdio.c, the function mt7530remove unconditionally disables regulator. However, the core and io power pointers for MT7531 and MT7621 remain NULL. As a...

Linux Kernel Security Vulnerabilities

The Linux kernel version 4.18 contains a security vulnerability. This vulnerability stems from the s390/cio subsystem, where the ccwdevicegetutilstr function does not check the return value of chpidtochp, which may lead to null pointer dereferencing...
